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 theywill not
change the state of polarization of the incident
beam.
