Paper Abstract

The performance status of silicon IR detectors, including spectral response, detectivity and operational temperature for use in the 2-2.5, 3-5, and 8-14 μm principal windows of the atmosphere, was recently briefly reviewed'. Such detectors operate under high radiant background conditions imposed by exposure of the detector to the ambient radiation of the atmosphere. In this review a more detailed description of the detectors is provided. It is extended to include the properties and performance of silicon detectors for use in the low background environment of space where backgrounds may be reduced by up to nine orders of magnitude. The effects of the reduced background promote high detector sensitivities, but produce unusual characteristics which are summarized. Such detectors are currently in use in the IRAS infrared astromomy telescope now orbiting in space.
