TL;DR: The ISOPHOT photometer for ESA's Infrared Space Observatory ISO as discussed by the authors uses extrinsic photo-conductors for astrophysical research at wavelength ranging from 3 to more than 200 μm.
Abstract: ISOPHOT, the photometer for ESA's Infrared Space Observatory ISO, will use extrinsic photo-conductors for astrophysical research at wavelength ranging from 3 to more than 200 μm. Doped silicon detectors will be applied as single pixels, linear and two dimensional arrays for photometry, polarimetry, mapping and in a low resolution spectrometer. Two dimensional arrays of doped germanium are foreseen as far-infrared cameras. During phase B of the project breadboard models of the most critical detectors have been built and tested with cryogenic multiplexing readout electronics.
