Paper Abstract

This paper describes a preliminary design for an imaging spectrograph that simultaneously covers the 2.15-5.2-micron spectral region with a resolution of 0.01 to 0.03 micron. Light entering the spectrograph through a slit is dispersed onto a 256 x 256 pixel InSb array by a novel spherical-faced prism/conic mirror combination. The use of a prism rather than a grating disperser allows more than a one-octave spectral interval to be covered with no moving parts. In addition, the prism optical efficiency remains high over the entire band covered. The simplicity and ruggedness of the design make it ideal for a space-borne instrument.
