Information

Infrared radiation: objects above absolute zero (-273.15°C) can radiate infrared energy outward. Infrared detectors are optoelectronic devices that can respond to external infrared light radiation, and are widely used in military, meteorological, agricultural, industrial, medical and security monitoring and other fields.

Since all objects have infrared radiation, there is huge background noise in the detection process, which leads to a decrease in the detection rate and responsivity of infrared detectors, and a high false alarm rate. Improving the detection rate and responsivity of infrared detectors and obtaining high-gain infrared detection are the research hotspots in this field.

Mercury cadmium telluride, vanadium oxide, and amorphous silicon materials have been extensively studied in previous studies. In recent years, since two-dimensional materials with zero or narrow band gaps can also be applied to infrared detectors, new principles and new devices have emerged one after another. However, the current infrared detectors based on these new material systems still need to overcome the problems of large-area uniformity of materials and improvement of device quantum efficiency and gain.

Measuring range of optical pyrometers

When the temperature to be measured is higher than the range that thermocouples can use, and where it is impossible or not suitable for installation of thermocouples, optical pyrometers can generally meet this requirement.
