ABSTRACT:
The polarizing beam splitting unit comprises a filter in the form of a layer of polarizing material which passes light in only one plane. This polarizing layer or filter is sandwiched between two transparent glass substrates, one substrate having a reflection-enhancing coating and the other substrate having an anti-reflection coating. In one embodiment the reflection-enhancing coating consists of a single layer of cerium oxide, and in a second embodiment the coating consists of layers of zinc sulphide, magnesium fluoride and silicon dioxide. In both situations the anti-reflection coating consists of magnesium fluoride. The polarizing beam splitting unit is employed in a composite photography system.
