Recommendations for the selection of infrared thermal imagers, what are the material compositions of

How to choose a suitable model of infrared thermal imager, first of all, you must first clarify your specific application needs, what specific scenarios are used, etc. Then you have to learn to look at several parameters of the infrared thermal imager, such as the infrared detector area array size, pixel spacing, netd, and so on.

The infrared detector chip is to the infrared thermal imager, which is the same as the CPU to the computer. The development trend of chips is the shrinking of pixel spacing and the gradual increase of area array size. The size of the detector surface array is an important indicator to judge the quality of the infrared thermal imager, and the relatively high-end product pixels in the civil infrared thermal imager are 640 512 384 288, and the infrared thermal map is clear and delicate.

In addition to area array size, cell spacing is also an important indicator. At present, the mainstream product of uncooled infrared detector chips has a pixel spacing of 12 microns. The smaller pixel spacing brings a more optimized optical system, lower power consumption, and a higher level of technology for the product.

netd is the noise equivalent temperature difference, and the lower the value, the clearer the image. Poor sensitivity, the observation point is overwhelmed by noise, "invisible", resulting in the inability to ensure the most basic safety functions in the field.

Frame rate refers to the number of images processed by the thermal imager in 1 second. The faster the sensor, the higher the internal circuit processing rate and the higher the frame rate. Thermal imagers with high frame rates are suitable for capturing high-speed movement of objects.

A good infrared thermal imager should have a frame rate of 25Hz 50Hz, otherwise it will not work on many occasions. The level of the frame rate directly indicates the performance and response speed of the infrared thermal imager. ”

Then you can take a look at the lens, spatial resolution, field of view, recognition distance and other indicators, and make a comprehensive judgment based on your specific needs. With these in mind, you can easily choose the right thermal imaging camera brand for you.

Choosing a shape? Or the type, the type according to your needs to be good, hunting to buy a hunting thermal imager, I like to hunt to choose the Arrow iray hunting thermal imager. You can choose whatever type you use for what you want.

A thermal imaging camera is generally composed of four parts: a detector, a signal processor, a display, and an optical system.

You should say that the detectors of thermal imagers are currently most abundant alum oxide and polysilicon.

Objects in nature that are higher than absolute zero (-273) are constantly emitting infrared rays. The infrared thermal imager converts the infrared radiation on the surface of the object into a visible image through an optical system, an infrared detector chip and an electronic processing system. To put it simply, the principle of a thermal imaging camera is to use temperature imaging to convert the invisible infrared energy emitted by an object into a visible thermal image.

The different colors on the top of the thermal image represent the different temperatures of the object being measured.

The high temperature of the infrared thermal imager can reach several or even thousands of degrees, and you can choose according to your needs.

When choosing an infrared thermal imager, you still have to choose a reliable brand! Generally, a better one like Fluke in the United States, even if it is a big brand, is quite an old brand, and the quality is very good. Choosing an infrared thermal imager is like choosing a camera, the first thing to consider is the clarity of the image, which is called spatial resolution in the index, which is the key to determining the quality of the lens, it is said that the smaller the number, the better; Secondly, we should consider the temperature measurement range, so that the temperature cannot be measured; After the general direction is determined, the details of the imager are considered, such as the automatic display of the maximum temperature, the presence or absence of a camera, and so on.

If you are used for temperature measurement in hospitals, stations, schools, etc., you can choose products from big brands, preferably with excellent R&D strength. Fotric Feizhi Branch, this brand belongs to Shanghai Thermal Technology Co., Ltd., has specially developed products for body temperature screening, such as automatic infrared body temperature screening instrument, AI temperature measurement, with fast, accurate and stable advantages. It is used in all kinds of hospitals, stations, schools, shopping malls, etc. across the country.

The company is headquartered in Shanghai, China, and has offices in Beijing, Wuxi, Nanjing, Jinan, Xi'an, and distributors in more than 30 countries and regions such as North America, Europe, South Korea, Singapore, Australia, etc., and has passed the international ISO:9001 quality system certification, the United States FCC certification, and the European CE certification.

Powerful manufacturers can provide you with professional products and services, fotric can provide professional product selection guidance and application case introduction, you can contact to see, I hope it will be helpful for you to buy.

Outdoor observation, industrial testing, temperature measurement, medical testing, monitoring, etc. Outdoor observation is generally used for hunting, and friends who often hunt at night generally use infrared thermal imagers, and there is nowhere to escape at night prey, among which the more well-known infrared factory is Arrow Optoelectronics.

There are many uses for industrial testing and temperature measurement, which can be used to measure the temperature of circuit boards, boilers and other medical tests to check some diseases of the human body.

The monitoring class can be used for forest fire prevention monitoring.

Infrared imaging is the use of human body thermal radiation to form an image, camouflage is the use of clothing color and the surrounding environment similar to achieve the purpose of camouflage, infrared imaging is generally used in the case of night and smoke, so they do not conflict, camouflage can still play its role.
