The Short Wavelength Spectrometer is one of the four instruments for the Infrared Space Observatory. The instrument operates at about 3 K. Employing diffraction gratings, if offers a resolving power between 1000 and 2000 in the wavelength range 2.45 to 45 micrometers . An additional Fabry-Perot interferometer offers resolutions between 25,000 and 30,000 in the range 12 to 45 micrometers . The instrument employs arrays of discrete detectors: InSb photo- diodes and Si:Ga, Si:Sb and Ge:Be photo-conductors. In the course of 1992, the flight unit was tested and characterized, with interruptions for minor modifications. The paper discusses the SWS design and its performance.
