A small LiF prism constant deviation spectrometer of the Czerny-Turner type is described. The transmission in the vacuum uv is at least twice that of a typical Ebert plane grating spectrometer. Although designed for planetary astronomy, it is also useful for airglow experiments and interplanetary missions where compactness and low weight are desirable. Without a drive, it weighs 850 g and is roughly 17 cm × 10 cm × 7 cm. However, it is mechanically rugged with high wavelength stability in flight (~1 Å). With 0.5-mm entrance and exit slits the spectral resolution is 16 Å at 1216 Å.
