Abstract

The optical design of a high-resolution 2-5-micron IR cryogenic echelle spectrometer which is currently under construction at NOAO is described. Special attention is given to the design and the purpose of the four units into which the spectrometer's optic can be divided: the foreoptics unit, the order-separation filter and slit unit, the echelle-collimator unit, and the camera unit. Optical specifications of each of these units are summarized.
