Abstract:
LCD projection systems that use reflective LCD imager units commonly use one or more polarization beamsplitters to separate the light incident on the imager from the light reflected by one or more respective imagers. The polarizing beamsplitters can be mounted onto a color combiner using an index matching layer and optical adhesive.
