We present a brief overview of the design and construction of two grating infrared spectrometer, a new 2D array, dual grating spectrometer for the 7.0 to 13.8 micron region, built at the University of Denver (DU). This instrument has been designed to fulfill specific scientific goals in astronomy while utilizing the array to its fullest extent. The instrument uses diamond-turned aluminum optics to allow warm optical alignment and eliminate differential contraction of the optics while operating at cryogenic temperatures. Two gratings are used in the optical design to provide a resolution of about 800. The entire assembly is cooled with a Gifford-McMahon refrigerator so that it may later be adapted for use during remote observing. The array is a Rockwell 128 by 128 Si:As BIB hybrid focal plane array sensitive from optical to 26 microns. The electronics package and software for readout were developed by Wallace Instruments and are already in use on our TNTCAM at DU. 'First light' is scheduled for late summer 1996.
