Abstract
A reflective microscope objective lens includes a concave mirror system that reflects incoming radiation, a convex mirror in optical communication with the concave mirror system, and a primary concave mirror in optical communication with the convex mirror. The concave mirror system includes a first concave mirror. The primary concave mirror focuses outgoing radiation onto a focal plane wherein the concave mirror system. Characteristically, the convex mirror and the primary concave mirror are arranged to direct light along a non-concentric path.
