Abstract
A method, element and system are provide for efficiently, accurately and without significant contribution of noise, splitting a beam of radiation or combining beams of radiation. In one embodiment of the invention, a beamsplitter front surface partially reflects incident radiation and refracts the rest of the radiation. The refracted radiation is completely reflected at a back surface of the beamsplitter and is completely refracted producing a parallel beam without creating any stray radiation or optical noise. This is accomplished using a p-polarized input beam and a Brewster angle geometry.
