Abstract. The Short-Wavelength Spectrometer (SWS) is one of the four instruments on-board ESA's Infrared Space Observatory (ISO), launched on November 17, 1995. The spectrometer covers the wavelength range of 2.38 to 45.2  img1.gifm with a spectral resolution ranging from 1000 to 2000. By inserting Fabry-Perot filters the resolution can be enhanced by a factor 20 for the wavelength range from 11.4 to 44.5  img1.gifm. An overview is given of the instrument, its in-orbit calibration, performance, observing modes and off-line processing software.

Key words: instrumentation: spectrographs - methods: data analysis - methods: observational - techniques: spectroscopic - infrared: general

* ISO is an ESA project with instruments funded by ESA Member States (especially the PI countries: France Germany, the Netherlands and the United Kingdom) and with the participation of ISAS and NASA. SWS is a joint project of SRON and MPE (DARA grants no 50 QI9402 3 and 50 QI8610 8) with contributions from KU Leuven, Steward Observatory, and Phillips Laboratory.
