Abstract
The design of a 360 mm focal length, f/3.6 camera objective to be installed on a Cassegrain spectrograph is described. The system, which is a four-eleMent, all-quartz arrangement with no aspheric surfaces, has a useful Spectral range from 350 to 1000 nm and an equivalent field of view of 4°.
