LHIRES III = Littrow HI REsolution Spectrograph. Lhires III is a Littrow type reflection spectrograph, allowing high-resolution spectra to be recorded on 6-8 magnitude stars with a 8"-16" telescope, and with a minimum of space and weight.
Spectrograph propotype - Custom design by me for use in undergraduate research at the University of Minnesota Duluth. Light passes through an optical slit and a 30mm f/2 achromat collimating lens and is reflected from a 1200-line-per-inch grating. The collimated light is focused by a 30mm f/3 achromat and the spectrum is recorded by an air-cooled Cookbook 245 CCD camera. Don't let the cardboard fool you. It works great!
