Paper Abstract

The Space Infrared Telescope Facility (SIRTF) will have three science instruments, the Infrared Array Camera (IRAC) which will obtain multispectral images between 1.8 micron and 26 microns, the Infrared Spectrometer (IRS) which is a set of two dispersive spectrometers covering the wavelength range between 2.5 and 200 microns, and the Multiband Imaging Photometer for SIRTF (MIPS) which is a general-purpose photometric instrument which operates between 30 and 1,200 microns. Taken together, the full wavelength range of these instruments extends from 1.8 micron to 1,200 microns, equivalent to nearly a factor of 700 in photon energy and diffraction limited image size. In addition to supporting this unprecedented spectral and optical coupling requirement, the SIRTF detectors must operate at lower temperatures than previously demonstrated and be optimized for new levels of performance in order to achieve the goals of the science mission. Thus, development of the detector arrays for the SIRTF instruments is one of the most challenging aspects of the instrument development activities.
