A long-wavelength spectrometer for the Infrared Space Observatory (ISO).
Abstract
A combination of Fabry-Pérots and a grating monochromator working in a parallel beam has been designed as a possible long-wavelength spectrometer for the ISO. It is a very flexible instrument and is capable of working at a high sensitivity and a range of resolving powers in the FIR, up to 104. The principles of the instrument's design are discussed and a brief outline of its capabilities given.
