Abstract
A telescope and beam expander assembly includes a primary telescope mirror. An optical element is spaced apart from the primary mirror. The optical element includes front and rear surfaces, wherein an outward facing aspect of the rear surface is mounted opposite the primary mirror and includes a reflective portion that forms a secondary mirror to reflect gathered light from the primary mirror toward a focal point. An inward facing aspect of the front surface includes a reflective portion that forms a secondary expander mirror configured to reflect a beam onto an inward facing aspect of the rear surface for beam expansion. The optical element can include a monolithic body of optically-transmissive material on which the front and rear surfaces are located.
