ABSTRACT:
An optical device for splitting an imaging light beam into at least three spacially and spectrally separated component beams which includes a plurality of surface pairs. Each of the surface pairs includes a first surface and a second surface. The first surface of each of the surface pairs is adapted to reflect a different one of the component beams. The second surface of each said surface pairs is adapted to reflect all of the component beams except for the component beam reflected by the associated first surface. A method for optimizing the performance of such an optical device is also disclosed.
