Scientific paper
The 'Isophot' photometry experiment of the IR Space Observatory allows multiband/multiaperture photopolarimetry, as well as multicolor polarimetric imaging and spectrophotometry. In order to cover the 2.5-240 micron wavelength range, five different detector materials have been used, arranged as two-dimensional arrays, linear arrays, and single detectors; a total of 223 different detectors is included. Accounts are presently given of the sources of noise in detector assemblies, the design of an integrating preamplifier unit, and the anticipated effects of high-energy radiation effects on detectors.
