Paper Abstract

We present a preliminary design for a red-sensitive spectrograph. The spectrograph is optimized to operate over the 600- 1000 nm spectral range at a resolution of R = λ/▵λ ~2000 and is designed specifically for the 2.7-m Harlan J. Smith Telescope at McDonald Observatory. The design is compact and cost effective and should have very high throughput. The principles of the design can be extended to other purposes, such as a unit spectrograph for the DESpec project or other projects that require good performance in the red. In this paper, we will discuss the selection of components as well as the choice of optical layouts and the theoretical throughput of the instrument.
