Abstract: A display system includes a reflective mode spatial light modulator for producing a pattern of polarized light, a light source for illuminating the spatial light modulator, and an optics arrangement. The optics arrangement includes a beam splitter element having a transparent substrate with a front face and a back face. The front face supports a beam splitter coating acting as a beam splitter. The back face supports a polarizer layer. The polarizer layer and the transparent substrate are configured to be refractive index matched to prevent the reflection of light at the interface between the transparent substrate and the polarizer layer. The beam splitter element is positioned in the optical path between the light source and the spatial light modulator in order to polarize and direct light from the light source to the spatial light modulator.
