Paper Abstract

Infrared detectors for operation at intermediate cold temperatures (190°K to 270°K) are finding many applications in night sights, airborne tracking systems, shipboard trackers and night viewing devices. Detectors, such as lead sulfide, lead selenide, photoconductive mercury cadmium telluride, and photovoltaic mercury cadmium telluride in single-element or array configurations, are well suited to such systems, and thermoelectric coolers are one convenient method of producing the required operating temperatures for these detectors. Recent advances in coolers, packages, and detectors have brought this total technology to a point of high reliability, long vacuum life, and higher detector sensitivity. This paper shows some of the options and tradeoffs which are open to the system designer for thermoelectrically cooled infrared devices.
