This is the ultraviolet spectrometer from the Apollo Telescope Mount (S082B). It was designed and developed at the Naval Research Laboratory by a group led by Richard Tousey. The unit flown on Skylab obtained spectra of different solar regions at great spectral and spatial resolution, covering a wavelength range from 970 to 3940 Angstroms. Spectra were recorded on photographic film on an attached camera. (see Catalogue #19820460000 for film magazine). A white light TV system allowed the astronauts to point the spectrometer. The artifact is a flight instrument intended for a never-flown second Skylab.
It was stored at the Marshall Space Flight Center until May 1986 at which time it was transferred to NASM.
