Can you imagine the application of poultry boning machine?

If a robot can remove bones from fresh chickens and keep the skin, is there anything it can't do? Maybe it can challenge itself to remove bones from the fish. Actually to make the robot has the ability to process chickens of different size and weight, and remove the bones without destroying the meat and skin, it is required to have accurate sense of space, which is the cutting-edge technology in the robots field indeed.

At present, Georgia institute of technology has developed a system, which can finish the boning process automatically with the use of advanced image technology and mechanical arm. It may make revolutionary impact on the poultry processing market. It adopts a 3D video system to decide where to cut, and then the mechanical arm will implement the boning process precisely, which can avoid the bone scraps left in chickens effectively.

According to the announcement of Gary McMurray, the head of food processing department at Georgia institute of technology, because of the different sizes and shapes of chickens, they established a set of induction linkage system to make it be suitable for all chickens. Chicken meat is the main agricultural product in Georgia, and the annual production value is as high as two billions of dollors.
This newly released robot adopts double degree of freedom mechanical arm, and the chicken are controlled by a six-degree of freedom mechanical arm. The video system detects the chickens using force feedback algorithm firstly, and then the six-degree of freedom mechanical arm moves the chicken to the cutting mechanical arm. And this system can also be applied to process other poultry after a simple adjustment, but there are also some people worry that once this robot is produced in a large sale, many people will be at risk of losing their jobs.

KUKA robot brings automation to poultry processing equipment

KUKA was established in 1898 by Johann Josef Keller and Jakob Knappich in Augsburg, and it initially focused on the indoor lighting and urban lighting industries. In 1973, KUKA developed the first industrial robot named FAMULUS in the world, and later KUKA concentrated its business on offering advanced automation solution for industrial producing process. Now it has been one of the leading industrial robots manufacturers worldwide.

KUKA robots can be used for materials handling, processing, stacking, electric soldering and arc welding, and it has been very popular in electrical automation industry, food, plastic and many other industries. It is reported that KUKA robot also brings automation to poultry processing equipment industry today.
KUKA has introduce two six-axis robots: KR30 and KR60. Both of the two robots are equipped with shields to protect them from erosion. The perfect combination of three-dimensional laser measurement system, PC assessment software and the conveyor software forms the core of the automation solution. A hanging conveyor transfors the poultry bodies that have processed by chicken evisceration equipments constantly by the speed of 170mm/s. So the robot must be able to keep up this speed and synchronize with the conveyor. At the same time, the three-dimensional laser measurement system can obtain the date of the whole surface of the poultry body precisely.
Becasue of the different size, weight, and manu other anatomical characteristics of different body, so measurement is very essential. Then the measured date will be transfered to the robot control system by PC assessment software, which can decide the cut date of each poultry body. On the basis of the date, the robot control system can calculate the relevant robot orbit, and then the first KR30 robot, which is equipped with double hook-and-loop will cut off the forehoof at the fixed position, and another KR30 robot was installed on the ceiling, and it will remove the rectum with the rectum cutter. By the remeasurement of the three-dimensional laser measurement system, a hanged KR60 robot equipped with a cleaver will broke the pelvic cavity of each carcass and pre-cut the breast. And then another KR60 robot opens the chest of the carcass, and cut the sternum from the middle precisely.
I believe that with the application of the KUKA robots, meat quality can be fast and accurately controlled and people's health conditions can be well improved.

What poultry farm equipments do we need to build a chicken farm?

Advanced poultry farm equipments are used to creat an ideal living environment for chicken flocks, and improve the production efficiency drastically. Today I will introduce some necessary poultry farm equipments that we need to build an automated poultry farm.

1. Heating equipment
During the brooding stage, especially in the cold winter, we can use electric heating, water heating, central heating, heated brick bed and other heating methods to keep chicken farm at proper temperature. Electric heating, water heating and central heating are relatively cleaner and healthier than other methods. While we have to be careful to prevent a gas poisoning accident if we use coal stove to heat, and heated brick bed might be fuel-consuming, but it is able to keep the temperature constant. Choose the suitable heating method according to the local conditions.
2. Ventilating device
For the open type chicken farms, we can regulate ventilation mostly depends on natural ventilation by controling the windows and skylight. But if in the hot summer, natural ventilation doesn't work neither, and mechanical ventilation should be considered. For closed henhouse, we almost reply on mechanical ventilation completely, and there are two types in general: aspirate type and exhaust type. Some chicken farms use aspirating ventilation, and some others use exhausting ventilation, and you can choose between the two types to suit the occasion.
3. Automatic chicken waterer

From the point of saving water and preventing bacterial contamination, nipple type chicken waterer is the most ideal choice, but because of the low quality and leaking problem, there are few chicken farms choose this type at present. The hanging chicken waterer is the mostly common type in most chicken farms. It is suspended from the ceiling through the hanging loop. The top water inlet tube connect with the main water pipe, and the incoming water flow into the water dish by control valve, which is both healthy and water-saving.
4. Automatic chicken feeder

Hanging chicken feeder is the most common type of automatic chicken feeder, and it is the combination of the appending machine of chain feeding machine. The construction of chicken feeding trough decides if the feed can be fully applied. It will cause feed wastage if the chicken feeding trough is too shallow, and tall feeding trough can greatly reducing feed wastage.
5. Egg laying case
Feeding meat chicken and laying hen can use double-layer egg laying case. Every 4 hens shares a case. The height of the upper footboard from the ground should not exceed 60cm, and the size of each egg laying case is approximately 30cm*30cm*38cm. Both side and the back side is grid, which guarantees the ventilation inside the case. Outside the bottom board there should be a impingement baffle to prevent the eggs slipping off the ground.
6. Dung floor cleaner

The general chicken farms clean the dung manually termly, and there are a few chicken farms use the manure scraper to clean the dung. But the steel wire rope of the manure scraper is easily broken, and the maintenance is not convenient, and it costs much. So it has not been widely used.
7. Poultry cage
Rearing chicken can use both halftone and vertical multilayer brooder, and rearing adult chicken can choose overlapped and stepped poultry cage. Poultry cage can make full use of the space and increase the feeding capacity. Besides, the good health condition can prevent epidemic effectively, it helps save much feed.
8. Lighting equipment
Currently most chicken farms use incandescent lamp as lighting equipment. Many chicken farms are equipped with timer to control the light switch automatically, to take the place of manual control switch, which guarantees the accuracy and reliability of lighting time.
9. Debeaking device
The automatic debeaking device is constructed by transformer, electrical machine, cooling fan and so on. It can finish the complete process of debeaking, hemostasis and detoxification quickly. The maximum temperature of the blade can reach as high as 1020℃ when connect the power, and a blade can process more than 20,000 chicken.

Application and Development on MEMS Optical Switch

MEMS is a mechanical and electrical integration device or system composed by highly integrating MEMS device such as micro structure and micro actuator whose geometric dimensioning or operation size is only at micrometer, submicron even nanometer level and controlling circuit on a very small space of silicon substrate or non-silicon substrate material. MEMS component has characteristic of small size, light weight, low consumption, small inertance and short response time. It can massively integrate microstructure of different function, sensitive direction and actuating direction together to conduct batch copy and massive production by micro electroforming method.

MEMS processing has similar technology with semi-conduct assembly circuit. Its primary characteristic is preparing MEMS by taking use of integrated circuit common technics like photoetching and mechanical erosion and acquiring tender moving structure by finally selecting corrosion technology to release structure unit on the basis of thin film deposition. Entering 90s century, with the successful application of deep groove mechanical erosion technology, bonding technology and other critical technology, bulk silicon micro mechanics gets rapid development and further exploits new technique combined of multiple bulk silicon process and surface micro mechanism technique. This makes MEMS technology not only get rapid development in sensor field but acquire unprecedented development in application and study in fields like optical fiber communication, micro chemical analysis system, DNA analysis and micro robot.
Optical fiber communication enters into optical fiber network age after realizing high speed and high capacity point to point transmission. MEMS has greatly wide application range in optical fiber communication field. Almost each constitutional unit in all optical networks can apply MEMS to manufacture component and develop MEMS. It is the synthesis of multiple technologies like mechanism, electricity, light, magnetism, chemistry, automatic control, sensor technology and information treatment. Make a comprehensive survey of optical fiber communication component development history, we can observe component development trend is bulk conglomeration optical fiber and MOEMS integration. In present situation that integration component is still not quite mature, MEMS or MOEMS optical component has emerged commercialized products.
MEMS technology one very important application in optical fiber communication network is taking use of tender moving micro-mirror to manufacture optical switch matrix. Tender moving micro-mirror can adopt up and down folding method, left and right shuffling method or rotation method to realize connection and break function. MEMS optical switch manufactured by MEMS technology integrates mechanical structure, micro touching component and micro optical component on a same substrate, equipping characteristic of compact structure, light weight and easy expandability. Compared with mechanical optical switch and waveguide mode optical switch, it has better excellent like low insertion loss, small intrusion tone, high extinction ratio, good repeatability and moderate response speed. It has nothing to do with wavelength, polarization, speed rate and modulation system. With long service life and high dependability, it can expand into massive optical cross liking switch matrix.
Global optical fiber communication market has experienced three years hibernation period. After that, with the Alcatel-lucent market share turning good and market value looking up, it rekindles hope springs in people. Though MEMS optical component manufacturers are amidst the winds of change and experience turn of the tide, MEMS technology application field is not only optical communication and still keep strong vitality. It is sure to get wide propagation and application in limitary and civilian fields like communication, navigation, sensor, medical, traffic and aerospace by virtue of its inherent feature and born advantage like research direction diversification, process technique pluralism, system monolithic integration, assembly and packaging unification and application field entirety.

The Mobility Hoists for the Patient

The inability to mobilize patients at home is one of the primary reasons that patients find it necessary to leave the home environment and enter a nursing home when they become temporarily or permanently disabled. Now, patients can solve this problem with portable electric patient lifts.
An electric patient lift may be either a sling lift or sit-to-stand lift. This is an assistive device that allows patients in hospitals and nursing homes and those receiving home health care to be transferred between a bed and a chair or other similar resting places, using hydraulic power. Sling lifts are used for patients whose mobility is limited. They could be mobile patient lifts or overhead lifts. The sit-to-stand lift is designed to help patients with some mobility but who lack the strength or muscle control to rise to a standing position from a bed, wheelchair, chair, or commode. They use straps, vests, or belts (as opposed to slings) to make the transition possible.

There has been considerable effort put forth by nursing advocacy groups to encourage hospitals and nursing homes to adopt "zero-lift" or "no-lift" programs in order to prevent orthopedic injuries in healthcare workers. However such Safe Patient Handling and Movement programs, which require the use of mechanical lifting aids, are sometimes difficult to implement. This is in part due to the time and effort required to safely use lift equipment. Transferring a patient with a lift takes between three and six minutes which are considerably longer than moving a patient manually. Lift manufacturers emphasize that the added time it takes to use lifts is worthwhile since mechanical lifting aids improve caregiver and patient safety and while also preventing patient falls.
Normally, much consideration is given to the patient's comfort and wellbeing during the transfer process. For some patients, the use of a patient lift is more dignified than transferring a patient manually while some consider being hoisted in a sling less dignified. Lifts can enable families or caregivers to mobilize patients in the home setting rather than forcing patients to be relocated to an institutional setting. Safe patient handling is especially important in the area of bariatric care. Bariatric patients who are classified as patient who weigh more than 300 pounds require additional staff training and specialized equipment for transfer, showering, toileting, etc.
While power patient lifts are often used by only one health care worker without assistance, most manufacturers require that two caregivers be present. However, the single caregiver approach makes the patient lift more usable in home care settings where there is often only one caregiver per patient. In either case, patient lifts require special care in their use, as any mistakes made may result in serious injury.

Introduction, Design Principles and Extensive Applications of Mobile Hoists

Nowadays, mobile hoists are extensively applied in hospitals, shipyards, loading docks and some other places where they are highly required to transport different types of objects for short distance. Since the mobility hoists are mounted on wheels, thus making it easier to carry the objects to the desired positions. For instance, by the help of electric patient lifts, the ambulance men can easily move the wounded patients to the ambulance so as to save time to rescue the patients. So, how much do you know about the introduction, design principles and applications of mobile hoists?

Brief introduction of mobility hoists
Generally, portable electric patient lifts are devices which can help move the injured people who got wounded during some traffic or construction accidents. At this moment, any manual lifting and handling may consequently lead to a severe strain on the patient because inappropriate handling will result in back pain or other injuries. However, by choosing appropriate lifting hoists for disabled and using them to move the patients to hospitals, the risks of sustaining injuries will be greatly reduced. Moreover, with the help of mobility hoists, the peasants are more likely to get rescued.
Design principles
The mobile hoists consist of frames, horizontal moving devices and beds. One of the most noticeable design principles of electric patient lifts is that the patients will feel very comfortable and convenient when they sit in the mobile device. Moreover, the patient will not be influenced by the movement of portable electric patient lifts, thus the patients do not have to worry about wound dehiscence and deterioration problems. More importantly, the structures of mobile hoists are very simple, which precisely means that the devices can be made into integration with the bed. So the devices can be applied in both hospitals and homes.
Extensive applications
One of the most common applications of the mobile hoists is found in a hospital, a nursing home, or some kind of ongoing care facilities. The mobility hoists are usually applied to move the patients for short distance. For instance, if a patient got severe back injury during a construction accident and could not stand on his own or with the help of other assistants, he must be transported to the nearest hospital to get treatment by the help of portable mobile patient lifts.
Furthermore, the mobility hoists are designed in a humanized way to help the patients call for emergent bailout depending on the degree of assistance required.
In conclusion, different kinds of mobile hoists like lifting hoists for disabled and portable electric patient lifts are playing indispensable roles for emergent bailout for the patients. The mobility hoists are not only reliable but also designed in humanized ways, which makes them popular for hospital applications and home uses.

Four Common Types of the Vacuum Pump

What is the vacuum pump? Vacuum pump, which involves the vacuum principle, physics, chemical and machinery, is one of the most widely used pumps. And, vacuum pump manufacturer offers all sorts of pumps now.
Jet-type
This type of vacuum pump involves the use of air-liquid mixture (this may refer to air, high pressure water or steam). It's typically comprised of an ejector, water tank, liquid-vapor separator, etc. Jet-type vacuum pump is characteristic of easy operation, power conservation and so on. Furthermore, you can use it to pump gas with corrosive or toxic ingredient unlike rotary vacuum pump.
Water ring vacuum pump
It works by means of water (working solution) as well as centrifugal force. People also regard water ring vacuum pump as a compressor. By applying this type of vacuum pump, you can benefit low manufacturing cost, easy maintenance, stable running, etc. Additionally, it's able to get rid of flammable or explosive gas because of isothermality compressed gas.
On the other hand, water ring vacuum pump can't serve the interest of customers with high efficiency requirement. This is because it only offers 30~50 perfect efficiency.

Rotary vacuum pumps
Rotary vacuum pump, comprised of body, rotor, spiral slice or spring, comes in single stage or double stage vacuum pump. It works by means of centrifugal force and tension of the spring. It's often seen in the chemical, light industry, medicine industry, etc.
Rotary vacuum pump features a flexible use - that means you can take it as low vacuum pump and meanwhile combine it with high vacuum pump. However, you can't take it as a compressor.
While, there are a few limits when using rotary vane vacuum pump. When pumping gas with high oxygen, explosive or toxic content, you'd better substitute another vacuum pump for rotary vacuum pump allowing for safety.
Reciprocating vacuum pump
The influence of reciprocating movement of piston allows pump to work. Reciprocating vacuum pump, made up of body, cylinder, crank axle, connecting rod, piston or gas valve, is available in vertical as well as horizontal type.
It's characterized by high efficiency and high vacuum degree, but features complicated maintenance. Currently, it works well to pump corrosive gas with no solid particles.
As vacuum pump features higher efficiency, stable performance as well as durability, it has won the trust of customers. Its popularity is also due to numerous types, offering customers enough space to choose which type is more suitable.

Which One Has the Good Market Outlook: Hot Dipped Galvanized Steel Pipe or Cold Galvanized Steel Pipe?

The galvanized steel tube has been used in water supply lines of buildings for about one hundred years. It has the good stiffness, impact resistance and wear resistance. The raw materials of galvanized steel pipes are easy to obtain and easy to machine. With these advantages and the moderate price, the galvanized steel pipes are generally acceptable in agriculture and as the water supply lines and fire pipelines in construction industry.

In order to increase the corrosion resistance of steel pipes, they must be galvanized. According to the different zinc-plate processes, galvanized steel pipe can be classified into two categories: hot dipped galvanized steel pipe and cold galvanized steel pipe.
Hot Dipped Galvanized Steel Pipe
Here is the process of hot dipped galvanizing: at first, remove the ferric oxide on the surface of the steel pipe; after then it's the solution cleaning process that put the steel pipe into the solution tank which is can be ammonia chloride solution tank or zinc chloride solution tank or the ammonia chloride and zinc chloride mixed solution tank; at last, put it into hot dipped tank. The essence of the hot dipped galvanizing process is that the molten metal reacts with the iron matrix and then the alloy layer is generated on the surface from the reaction to protect the steel pipe from corrosion. The hot dipped galvanizing has the advantages of high uniformity of zinc coating, high coating thickness and strong adhesion and the hot dipped galvanized steel pipes has the long service life.
Cold Galvanized Steel Pipe
The cold galvanizing is equivalent to the electro galvanizing. It has the completely different galvanizing process to the hot dipped galvanizing. In the process of hot dipped galvanizing, the steel pipe is put into the molten zinc liquid at the temperature of 450 to 480 centigrade. But the process of cold galvanizing is the electroplating method at the normal temperature. The zinc coating mass of the cold galvanized steel pipes cannot measure up to that of hot dipped galvanized steel pipes. And what is more serious is that the cold galvanized steel pipes are prone to cause water solution when they are used as water pipes and gas pipes, so that the cold galvanized steel pipes have already banned in many countries.
Most of the regular manufacturers have already abandoned the electro galvanizing to meet the best quality requirement and galvanized pipe suppliers have barely supplied the cold galvanized steel tube today. The hot dipped galvanized steel pipes has the much thicker zinc coating, the better corrosion resistance and its service life can be 30 to 40 years! The cold galvanized steel pipe is generally eliminated, but the hot dipped galvanized steel pipe has the great market prospection.

Fuctions and Classifications of Optical Isolator

Optical isolator is a kind of free space isolator. It is common optical equipment and device used in optical fiber communication system and precision optical measurement system. It is a kind of passive optical component that allows only unidirectional light goes through. Its working principle is based on the non-reciprocity of Faraday rotation. The light reflected by the optical fiber echo can achieve good isolation effect by optical isolator. So optical isolator is to allow light to one direction and block it to the opposite direction by the passive components. Its function is to limit the direction of the lights to make the lights only go to a single direction, and in this way it can improve the efficiency of light transmission. The characteristics of optical isolator are high isolation efficiency, low insertion loss, high reliability and high stability.

Let us have a look at its working principle and function. In detail its role is to prevent the back lights made in the light transmission process for a variety of reasons do harm to the light source and optical system. For example, if between the semiconductor laser light source and optical transmission system there is an optical isolator installed; this can largely reduce the bad effect that the reflected light does to the spectrum of output power stability. In the optical communication system, we install an optical isolator in every other distance; we can reduce the power loss. Therefore the optical isolator plays an important role in optical fiber communication system, optical information processing system, optical fiber sensing and precision optical measurement.
There are a wide variety of optical isolators in the world. According to its internal structure it can be divided into block type optical isolator, fiber optical isolator and the waveguide optical isolator. There are also other kinds, such as in-line isolator and so on.
1. Block type optical isolator
This kind of isolator is a discrete component structure. It means getting together the gap of optical isolators in the light path structure through the lens of the gathered polarizer and Faraday rotator. This kind of device is relatively mature in technology, now it is commonly used in the market. The opto isolator manufacturer produces many products for the use in optical systems. However, it also has some disadvantages. It needs many optical devices, so it is relatively huge.
2. Fiber optical isolator
This type refers to do some work on the optical fiber end surface, such as polishing coating in the light path structure of isolator. It has the following characteristics. It has small size, light weight and good resistance performance to mechanical vibration. However, making the devices we should use the special optical fiber, and it requires high machining accuracy, complex producing technology and much manufacturing cost.
3. Waveguide free space isolator
Waveguide optical isolator belongs to the integrated optics. It is made on the basis of lithium niobate with Ti, and it is processed by deposition, photoetching, spreading and it is made into magneto-optic waveguide. After that it is processed together with other components. In this way we have this kind of optical isolator. It has small volume and light weight. Its thermal stability and mechanical stability are good. But due to the immature technology, its real performance still has some disparity with the required standard.

The Current Situation and Future Direction of China Washing Machine Exports

China washing machine exports enters rapid growth period since 2003, but since the start of 2009, under the influence of global financial crisis, China washing machine exports have been great changes. After the financial crisis China washing machine exports have been reduced, but compare with other countries, have gained, rather than lost in the international market share.

In 2012, the proportion of China washing machine exports in total sales was about 35% .The exports of China washing machine products to Japan , the united states and some other developed area has maintained its equilibrium, yet the sales of cheap washing machines grow faster in the emerging markets. In the background of a worsening environment for exports, the washing machine export growth will slowdown in the future, but as soon as home appliances policies being withdrawed, China washing machine companies would find it difficult to sell products at home, and the importance to sell abroad would showed up.
On the other hand, in Asia, Africa, and Latin America, especially Countries like Indonesia, Egypt who has large population start to show its huge consumption potential. In 2012,the Exports of washing machine to Indonesia, Egypt both exceed that to us, exports to Indonesia was twice to us:china exported 373700 washing machines to Indonesia,22.38% increased year-on-year,189300 washing machines to Egypt, 14.48% increased .The new Market above-mentioned rise rapidly, which makes exports more important. Insiders estimated that the exports of cheap washing machines and other appliances will keep growing, and Asia, Europe and Latin America will still be major markets to China.
So far with the whole situation to China washing machine exports at the present state, washing machine manufacturers from Cixi,Ningbo city who make middle-low-priced products has no price advantage after appreciation of the RMB, at the same time market who need middle-low-priced products becomes Saturated. From the washing machine development in China, it is doing increasingly well in the high end of the market, in this case China washing machine exports should try to improve the product structure, export on high-end way.
By comparison, foreign companies seem more optimistic in exports. cause foreign companies operates global, some of its manufacturing bases which operating cost too much have been closed , reduced or moved to China in a depressed economy, no doubt it has larger exports in China. For many washing machine manufacturers in China who simply produce on contract for global brands, profit margins are already razor-thin, and raising prices could hurt business, they have no price advantage in middle-low-priced products.

Selection Tips for Automotive Radiators

The operating temperature of an engine of a car is critical because engine could work well within certain range of temperature. The operating temperature could ensure longevity and high performance of an engine, but it can also ruin the engine when it is too high. Engine generates a large amount of heat which could damage itself, and therefore, an all aluminum radiator for the engine is very necessary. The automotive radiators dissipate heat generated by the engines through the circulation of coolant. They have certain period of service life, and therefore, when you select new auto radiators, you could consider the following tips.
Material which is made for manufacturing the racing radiators should be taken into consideration at first because heat transfer coefficients of different materials are different. In the market, the automotive radiators are usually made from aluminum and copper because these materials have good heat dissipation ability. But automotive specialists suggest that aluminum racing radiators are more favored for cars because aluminum is stronger and lighter. On the contrary, copper is softer, and it is heavier than aluminum by 60% when they are made into the same automotive radiators. Aluminum auto radiators could provide excellent heat dissipation effect and fuel saving advantage.

Structure of the auto radiators requires more attention from you because it also determines the heat dissipation effect of automotive radiators. Structure of a radiator could be divided into down-flow radiator and cross-flow radiator according to the travelling ways of coolant in the radiator. The type of the structure could be determined by packaging limitations of engine bay. An original type of engine bay requires a down-flow radiator while a modified engine bay could use a cross-flow radiator. When it comes to comparison, the cross-flow radiator is more efficient than the down-flow radiator.
The auto radiators could be selected according to the modes of cars. Business cars could use ordinary automotive radiators which could serve the vehicles fully. Racing cars should be equipped with racing radiators because engines in racing cars generate more heat and have higher requirement for the heat dissipation performance of auto radiators.
In order to select good auto radiators, users should know more knowledge about radiators so as to select appropriate and high performance radiators. At the same time, automotive radiators should be purchased from reliable automotive radiator suppliers so that the radiators have excellent after service, proper design, stable working performance and reliable quality.

Classification, Effect, Working Principle and Characters of Optical Isolator

Optical Isolator is an optical passive device that only allows passing through of one-way light, whose effect is to limit direction of light and keep light transports in a single direction. Thus, via fiber optic cables echo reflected light can be isolated by Optical Isolator to improve optical transmission efficiency. This article, I will focus on classification, working principle and features of Optical Isolator.

For the purpose of satisfying demand of different fields, Optical Isolator Manufacturer produced various kinds of Optical Isolator, mainly include: In-Line Isolator, Free Space Isolator and Fiber Optical Isolator and so on. It is widely used in optical fiber amplifier, fiber laser, fiber CATV net and satellite communication and so many fields. Generally speaking, wavelength of Optical Isolator is from 800nm to 1300nm, of course, there are some exceptions.
Now let's have a look at working principle of free space isolator: magneto-optical crystal Faraday Effect. As shown in the following, forward incoming signal light turns to linearly polarized light through polarizer. Faraday rotation magnetic media and external magnetic field make signal light have a 45 degree rotation at right. To backlight, when linearly polarized light pass through place media, its direction also have a 45 degree turning at right, thus, make polarization direction of backlight cross-cut with polarizer to completely block the transportation of reflected light.
Besides, follow me to effect of Optical Isolator. That is to prevent all bad influences on light source and light system caused by after transmission light. For example, install an Optical Isolator between diode laser source and light transmission system can decrease bad effect that reflected light have on stability of spectra of the light output power. At the same time, in the system of high speed direct modulation and direct detection of optical fiber communication, backward transmission light will produce extra noise which can make the system performance degradation. At this time, Optical Isolator is needed to remove the noise. Apart from these, installation of in-line isolator at both sides of fiber amplifier can improve working stability of fiber amplifier.
The most important thing is the characters of Optical Isolator. Due to its high isolation, low insertion loss, high reliability, high stability, extremely low polarization loss and polarization mode dispersion, it is widely accepted by customers all over the world. That's why so many Optical Isolator Manufacturers are flooding into the international market to challenge the fierce competition and manage to make their product a good selling point.
