TL;DR: A stressed Ge:Ga infrared detector was tested in various operating conditions and background-limited performance was demonstrated at photon backgrounds down to <108 photon s−1 cm−2.
Abstract: A stressed Ge:Ga infrared detector was tested in various operating conditions. Background-limited performance was demonstrated at photon backgrounds down to less than 10 to the 8th photon/s sq cm. The optimal operational parameters were determined.

TL;DR: One of the four focal plane instruments of the Infrared Space Observatory (ISO) is ISOPHOT, a photopolarimeter for the wavelength region 3 to 200 microns.
Abstract: One of the four focal plane instruments of the Infrared Space Observatory (ISO) is ISOPHOT, a photopolarimeter for the wavelength region 3 to 200 microns. Each experiment occupies a quadrant of the focal plane. The telescope beam is directed into each experiment by means of a pyramid mirror and by tilting the satellite. The diameter of the unvignetted field of view is 3 arcmin or 7.85 mm in the focal plane (1 mm = 23 arcsec). The temperatures provided are 3 K for cooling the detector systems and 8 K for the experiment structure. Available detectors are described along with the current status of the experiment.
