Abstract

We have designed an immersion echelle-prism spectrograph for the remote detection of chemicals in the atmosphere. The instrument operates in the 2 and 3 micron atmospheric windows, and provides maximum throughput at 0.1 cm^-1 resolution. Crossed dispersers consisting of a high order silicon immersion echelle (13.5 grooves/mm) and 43 degree immersion prism (Rutherford prism) are combined in a Littrow configuration to generate a two-dimensional spectrum in the image plane.
