The three science instruments in the Space Infrared Telescope Facility (SIRTF) require infrared detectors and readouts that operate at cryogenic temperatures with very low dark current and read noise. Detectors are being developed for the spectral region between about 2 micrometers and 200 micrometers. This paper describes the performance requirements and updates the progress to date for several different development activities, encompassing indium antimonide detector arrays, arsenic doped silicon impurity band conduction (IBC) detector arrays, antimony doped silicon IBC detector arrays, and germanium photoconductor arrays. Progress is also reported for very low noise cryogenic silicon readout devices.
