Image System For The Middle Ultraviolet

A TV camera system has been developed for imaging ultraviolet sources in the middle ultraviolet region of the spectrum. The imager consists of 200 mm focal length ultraviolet optics with a focal ratio of f/2.7, has a resolution of better than 1/3 milliradian, a 25 mm image intensifier, a filter wheel with filter wavelengths from 2150 to 3250 Angstroms and a CCD focal plane array of 380x488 elements. The performance characteristics of this imager will be given and examples of images of ultraviolet sources that have been obtained will be shown.
