Good company in a journey makes the way seem shorter. — Izaak Walton

The UVC was one of the experiments deployed on the lunar surface by the Apollo 16 astronauts. It consisted of a telescope and camera that obtained astronomical images and spectra in the far ultraviolet region of the electromagnetic spectrum.

The Far Ultraviolet Camera/Spectrograph was a tripod mounted, f/1.0, 75 mm electronographic Schmidt camera weighing 22 kg. It had a 20° field of view in the imaging mode, and 0.5×20° field in the spectrographic mode.[1] Spectroscopic data were provided from 300 to 1350 Ångström, with 30 Å resolution, and images were provided in two passbands ranges, 1050-1260 Å and 1200-1550 Å.[2] There were two corrector plates made of lithium fluoride (LiF) or calcium fluoride (CaF2), which could be selected for different bands of UV.[1] The camera contained a cesium iodide (CsI) photocathode and used a film cartridge[2] which was recovered and returned to earth for processing.
