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.

Testing and characterization of the short-wavelength spectrometer for Infrared Space Observatory

Results of the ground test and characterization program show that the performance of the SWS is well within its specifications. The procedures for ground testing and calibration are tuned to achieve commonality with in-orbit procedures. This strategy optimizes the development of data analysis procedures and allows a fast in-orbit check-out and update of the calibration.
