Abstract

The newly designed Zeiss spectrophotometers cover the total spectral range used in ground based astronomy. The first instrument for 1-5 pm contains an In:Sb photovoltaic detector and the second instrument for 5-14 pm a Si:Ga photoconductor. The instruments are nearly identical in their configuration. They are independent of liquid cryogens due to their closed cycle refigerator system. The internal cooled field optics has been optimized for minimum thermal background radiation. The medium spectral resolution of 50 - 100 is achieved by circular variable filters. The instruments fully operate under microprocessor control which provides rough data eva-luation (Lock In procedure) as well as data storing.
