Paper Abstract

The ESO Infrared Photometer/Spectrophotometers are at present in use on the 3.6 m and 1 m telescopes at our observatory at La Silla in Chile. Each instrument consists of a photometer mount and two detector units, a solid N2 cooled (~55°K) InSb detector for the 1-5 μm region and a bolometer, for the 2-25 μm region, which is cooled to ~l.2°K by pumping on liquid helium. Early next year, two new photometer mounts will be installed on the 2.2 m and on the 3.6 m telescopes, both using an f/35 chopping secondary mirror. The detector units are mechanically and optically identical for these 4 instruments in order to facilitate their operation and maintenance at the observatory. A description of the detector units follows.
