ABSTRACT:
An optical color separation and synthesis system is constructed according to a method, in which four first to fourth polarization beam splitters are arranged in such a manner that polarization separating surfaces of the polarization beam splitters form an X-shape, a predetermined gap is formed between facing surfaces of the polarization beam splitters before bonding the polarization beam splitters onto a base platform, and thereafter a frame comprising an opening in a middle portion thereof and a stepped portion to be bonded to an optical function plate in a peripheral portion thereof is secured to any of the first to fourth polarization beam splitters.
