Abstract
Light beam splitting and combining system integrate some optic elements into the interfaces of two sets of prisms. Films for reducing stray color beams are coated the interfaces. Two sides of bigger prisms are faced to each other. Another side of each bigger prism is attached to the hypotenuse side of one small prism. A dichroic mirror and PBS are coated on those interfaces. Modulators are parallel to and positioned on the sides of the small prisms and a third side of one bigger prism. Such a system may be applied to a projector.
