Method for reducing the thermal background radiation of spectroscopes and detector assembly for use in the infrared range

The method involves cooling a detector heat shield (20) and arranging a filter unit (21) within an evacuated area (17). A diffractive or dispersive optical system (11) is arranged before an aperture (22) facing away from the detector (16) for generating a spectrum. The filter unit is cooled to the temperature of the detector. The detector is shielded from unwanted background radiation by the cooled filter unit. An independent claim is included for a detector arrangement for use in infrared range.
