Polarization Cube Beamsplitters

Beamsplitters are optical components used to split input light into two separate parts.Cube beamsplitter consists of a pair of right angle prisms cemented together with a dielectric coating on the hypotenuse of one of the prisms. An anti-reflection coating has been applied to each outside surface of the beamsplitter to achieve less than 0.2% reflection per surface.
