Non Polarization Beamsplitter Cube (NPBS Cube)

Non Polarization Beamsplitter Cube ( NBPS Cube ) consists of a pair of precision high tolerance right angle prisms cemented together with a metallic-dielectric coating on the hypotenuse of one of the optical prisms. The low polarization dependence of the metallic-dielectric coating allows the transmission and reflection for S - polarization and P - polarization states to be within 5% of each other. This Beamsplitter means that they will not change the state of polarization of the incident beam. 

Non Polarization Beam splitter ( NPBS ) is similar to Polarizing Beam Splitter ( PBS ), and the features of Polarizing Optic NPBS are as follows:
Low polarization dependence;
Low power application;
Not change the state of polarization of the incident beam.
