ABSTRACT:
A beam splitter and method for separating a polychromatic light beam into a plurality of spatially and spectrally separated color component beams which are focused at a common image plane. The beam splitter includes a plurality of dichroic surfaces which each reflect light in a first spectral range, a second spectral range, or a third spectral range, and transmit light in spectral ranges other than the one it reflects. The beam splitter also includes a plurality of reflective surfaces which are each disposed parallel to one of the dichroic surfaces and which each reflect light in at least two of the first, second and third spectral ranges. The relative distances between the dichroic surfaces and corresponding reflective surfaces are such that the path lengths of the color component beams are approximately equal.
