Figure 12.
A prototype implementing an astronomical Keplerian telescope using polarizing beam splitters and spherical mirrors. The objective assembly (top) is composed from the magnifying element of a MicroOptical display system which includes a polarizing beam splitter, a quarter wave plate, and a spherical mirror (top). The ocular assembly (below) is constructed from a polarizing cube beam splitter, a quarter wave plate and a conventional plano-convex lens that was silvered on the convex surface. A dark occluder is visible behind the image of the ocular spherical mirror.
