Scientific paper

A long-wavelength spectrometer (LWS) for the infrared space observatory, which consists of two Fabry-Perot interferometers working in conjunction with a grating monochromator, is described. The spectrometer is a very flexible instrument which operates from 50 to 200 microns and is capable of different modes of operation covering the resolving power range from 100 to 10,000. The LWS design which is divided into three subsystems, the collimator subsystem, the interferometer unit, and the grating-collector subsystem, is discussed. A brief outline of the instrument's capabilities is given.
