Abstract
There is disclosed a ring field relay optical system incorporating concave spherical mirrors and including magnification achieved, at least partially, by a convex spherical mirror. In further modifications, aberrations introduced by the convex mirror are controlled by lens groups formed from fused silica. The system is usable from the visible through the deep ultraviolet portion of the spectrum.
