Abstract
In the present work results of study of a photodetector with thermoelectric cooler for operation in the spectral range 3-5 μm have been presented. As a material for sensitive elements Cd1-xHgxTe (x=0.28-0.30) solid solution single crystals were used. For cooling a photosensitive element three-cascade thermoelectric cooler providing cooling on a temperature level ~ 200 K was used. It is established that the value of the specific detectability of developed photoreceiver at ~ 200 K on λ= 4,5 λm wavelength equals DλMAX greater than or equal to 1 x 1010 cm x Hz1/2W-1.
