Abstract
An infrared detector has its sensor chip assembly (10,12,14) cooled to a relatively low temperature required for its operation, whereas a preamplifier (56) required to be positioned close to the sensor chip assembly and which generates considerably more heat than does the sensor chip assembly, is thermally isolated from the sensor chip assembly and its support (16) and is cooled to a higher temperature to thereby significantly reduce the power dissipated to the coldest refrigerator stage (90).
