Paper Abstract

An optical system is described which is corrected for spherical aberration, coma, astigmatism, Petzval curvature, longitudinal and lateral color, secondary color, spherochromatism and chromatic variation of all the field aberrations. It has very good performance on a flat image over an extremely broad spectral range, from the ultraviolet to the infrared. It has also been designed to cover a very broad temperature range. All spherical surfaces are used, and only one glass type. With BK-7 glass, the catadioptric design has a spot size of four arc-seconds over a 3 degree diameter field of view flat image at f/2.5, over the whole spectral range of 0.3650 μ to 2.0 μ. Predicted performance is essentially unchanged over a temperature range of 1000oC.
