A grating spectrometer for use from 1-5 μm with all optics including two gratings cooled to cryogenic temperatures is described. In order to make the optical system as compact as possible, the novel design uses cylindrical teleconverter optics. This enables a resolving power of R ˜ 3 × 103 to be achieved at 2.3 μm with a 2.7 arc sec entrance aperture on the Mount Stromlo 1.9-meter telescope. Also described is a second-generation spectrometer, employing a cooled solid Fabry-Perot etalon for a higher resolution capability, that is currently under development.
