-8- ABSTRACT: "Infrared receiver having a cooled radiation detector" An infrared receiver having an infrared radiation detector (26), which is cooled by means of a cold-gas engine, the thermal contact between a cooling surface (63) of the cold-gas engine and the radiation detector (26) being obtained by an elastic thermally conducting bridge (65), The cylindrical bridge (65) is constituted by a plurality of windings of a metal strip. Due to the presence of the bridge (65), good thermal conduction and furthermore compensation for differences in thermal expansion coefficients of the materials used are obtained, The infrared receiver is particularly suitable for night vision apparatus.
