Paper Abstract

The Infrared Space Observatory (ISO) is essentially a cooled 60cm diameter telescope with four flocal plane instruments operating at cryogenic temperature. One of these instruments, the Long Wavelength Spectrometer (LWS), offers spectroscopic capability over the wavelength range 43 micrometers to 198 micrometers , with a choice of either a mid-resolving power mode (R approximately equals 200) or a higher resolution mode (R approximately equals 10000). For testing the Flight Model of the LWS, it is necessary to establish many of the operating conditions which will apply when it is operating in space, using a specially constructed calibration facility. These tests have enabled the operating modes of the LWS to be refined, as well as measuring its operational performance and establishing a calibration database. This data will provide the initial calibration for the LWS when operating in-orbit.
