ABSTRACT:
An infrared receiver having an infrared radiation detector cooled by means of a cold-gas engine, the thermal contact between a cooling surface of the cold-gas engine and the radiation detector being obtained by an elastic thermally conducting bridge. The cylindrical bridge is comprised of a plurality of turns of a metal strip. Due to the presence of the bridge, a good thermal conduction and further a compensation for differences in thermal expansion coefficients of the materials used are obtained. The infrared receiver is particularly suitable for night vision apparatus.
