Paper Abstract

This paper describes the Cerro Tololo Infrared Spectometer (IRS), a general purpose cooled-grating spectrometer designed for 4-m and 1.5-m telescopes, which was recently upgraded to operate with the Santa Barbara Research Center 62 x 58 InSb array. Special attention is given to the optical and the mechanical designs of the IRS, its data acquisition and instrument control systems, and the operation characteristics of the instrument and the dewar. The updated IRS provides resolutions from about 0.9 micron to 5 microns.
