Paper Abstract

The Long Wavelength Spectrometer is a focal plane instrument for the ESA Infrared Space Observatory, operating over the wavelength range 45 to 180 pm. To perform the alignment, testing and calibration of the spectrometer requires much of the telescope optics, instrument fixtures and temperature conditions to be replicated or simulated in the laboratory. In addition, facilities for achieving photometric and spectral calibration are required. A cost-effective solution to the problem is described here which involves a minimum size for the test cryostat.
