Scientific paper

The Orbiting and Retrievable Far and Extreme Ultraviolet Spectrometer (ORFEUS) to be flown with the ASTRO-SPAS satellite is described. The ORFEUS instrument complex consists of a 10-m on-axis telescope with a focal length of 2426 mm, an Echelle spectrometer for the FUV region, and a Rowland spectrometer for the EUV region. The main objectives of the ORFEUS are spectroscopic measurements of cosmic radiation sources in the temperature region between 10 exp 4 K and 10 exp 6 K. The paper includes configuration diagrams of the ORFEUS and the ASTRO SPAS.
