Polarization Cube Beamsplitter

Polarizing Cube Beamsplitters split randomly polarized beams into two orthogonal, linearly, polarized components.S-polarized light is reflected at a 90deg, Angle while P-polarized light is transmitted.Each beamsplitter consists of a pair of prrecision high tolerance right angle prisms cemented together with a dielectric coating on the hypotenuse of one of prisms

1. Overview

Beamsplitter is also a kind of filter,it is used to split or combine laser beam. However Polarization BeamSplitters are used to split or combine two perpendicular polarization laser beam. The performance of beam splitter depends on the coating specifications. For the coating curves of each types of beamsplitters, please refer to Coating section for more information.

To select a suitable beamsplitter, you need to consider the type, coating, transmission range and damage threshold.
