Good quality products, trusted supplier!

—— VIctor Osorhan

Outstanding product quality & service! We have worked with a lot of companies in Asia, many times the quality is great but the communication is too complicated. In case of Shifang Yuantong Optical Instrument the quality of the products is excellent AND the communication is outstanding easy and fast

—— Matthias Frisch

8x33 Monocular ED I ordered only one as sample. They shipped fast, had in stock. It is of good quality, very sharp optics, focus smooth and fast.

—— Giorgio Pattarini

Very high quality product! Supplier is attentive, knows the business and is always willing to help. Very pleased with the whole process.

—— Ana Silva

Binocular 8x40 Porro FOV 140m/1000m I ordered one piece as sample, and they shipped promptly from stock. Well made product, very sturdy; the prism are mounted into a cradle inside the housing. The objective is recessed and protected. Focusing wheel is a bit hard but precise; eyepieces are stable. Good optics with green coatings, prisms with black c

—— Milucci Christian

I just wanted to say THANK YOU! :-) ^_^You've always responded to all my questions very promptly and with all the details i asked!You worked with me offering different options when appropriate:shipping options, or neck strap options,or boxes, You've always nice to me! so Thank you!!!

Do you know what the principle of infrared thermal imager is? How does it measure temperature without touching it?latest company news about What is the principle of infrared thermal imager?  0

Infrared thermal imager is a device that uses infrared thermal imaging technology to convert the thermal distribution data of the target object into video images by measuring the infrared radiation of the target object, through photoelectric conversion, signal processing and other means.

The specific working process of the infrared thermal imager is to receive the infrared radiation energy of the measured target through the optical imaging system, and then act on the photosensitive element of the infrared detector, and obtain the infrared thermal image after the subsequent circuit and signal processing. Its essence is to image the energy in the infrared band, and then through pseudo-coloring processing, different colors represent different temperatures, so as to intuitively see the temperature distribution on the surface of the object. Moreover, the infrared thermal imager can not only achieve non-contact temperature measurement, but also the measurement accuracy can be controlled within ±0.2°C.

Infrared thermal imager technology is relatively mature, but also has some small shortcomings. For example, because the measurement method of infrared thermal imager is non-contact, it is easily affected by the external environment, resulting in inaccurate measurement results. The instrument is calibrated under the environment; moreover, the body radiation generated by the internal components of the infrared thermal imager will also affect the detection results.latest company news about What is the principle of infrared thermal imager?  3

The advantages of infrared thermal imagers are also very obvious. Because the infrared thermal imager is imaged by collecting the infrared radiation energy of the target, it can work normally in the day or night; in the harsh rain and snow weather environment, it can also take advantage of the long infrared wavelength to use Thermal imager for observation. For concealed targets, because the infrared thermal imager is not detected by light, it will achieve the purpose of identifying camouflage.

 

Although our impression of infrared thermal imagers generally stays on body temperature detection, infrared thermal imagers also have many applications in other fields, such as long-distance detection and inspection of high-altitude pollution sources in chemical enterprises and volatile organic compound emissions from the top of tank farms. Imagers can provide temperature measurement and thermal state analysis, which facilitates long-distance, non-contact on-site law enforcement inspections for law enforcement officers; for example, in the medical field, infrared thermal imagers can collect human infrared radiation through thermal imaging diagnostic systems, and finally convert them into Images of different colors, thus reflecting the nature, degree, and scope of pain.
