Paper Abstract

We report the first application of an aberration corrected, concave holographic grating to a stellar spectrograph for conventional astronomy with telescopes of moderate aperature. The spectrograph is comprised. of three modules: the first contains field. viewing optics and physically interfaces the instrument with the telescope; the second holds a comparison source and optics for f/ratio matcLing and slit viewing; and the last is a modified commercial spectrometer incorporating an optimized concave holographic grating. Astronomical dispersion is 160 Å/mm. Wavelength range is 3700 to 6600Å. Performance of the instrument is illustrated by spectra of MK standards.
