Non-Polarizing Cube Beamsplitter 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
prisms. The low polarization dependence of the metallic-dielectric
coating allows the transmission and reflection for S- and P-polarization
states to be within 5% of each other. This means that they will not
change the state of polarization of the incident beam.
