Abstract
A reflective optics system that preferably requires the presence of both convex and a concave mirrors that have beam reflecting surfaces, the application of which achieves focusing of a beam of electromagnetic radiation onto a sample, (which can be along a locus differing from that of an input beam), with minimized effects on a polarization state of an input beam state of polarization based on adjusted angles of incidence and reflections from the various mirrors involved.
