Abstract:
A projector apparatus for separating white light emitted from a light source into a plurality of component rays respectively having wavelength ranges at a color separation/synthesis section and spatially modulating said component rays by reflective type spatial modulators respectively, and then synthesizing said spatially modulated component rays at said color separation/synthesis section to be emitted, whereinsaid color separation/synthesis section comprising comprises:a glass block body comprised of a plurality of glass blocks including a triangular glass block, a four sided polygonal glass block and a five sided polygonal glass block, said glass blocks being combined together such that corresponding sides are in close contact with each other; anda plurality of dielectric multilayer films respectively disposed between said glass blocks, for making predetermined component rays out of said plurality of component rays included in said white light enter said reflective type spatial modulators by reflection and transmission, and for synthesizing emitted rays from said spatial modulators and emitting a synthesized ray in a predetermined direction.
