Refrigeration infrared detectorIt is a high-precision photoelectric sensor based on semiconductor materials such as mercury cadmium telluride, indium antimonide, type II superlattice, etc. It uses active cooling technology (such as Stirling cooler, liquid nitrogen cooling) to reduce the operating temperature to a low level (usually between -150 ℃ and -200 ℃) to achieve high sensitivity detection of medium to long wave infrared radiation.
