Non-Polarizing Cube Beamsplitters also called NPBS Cube is a more sophisticated type consisting of two right- angle prisms cemented together at their hypotenuse faces.The cemented face of one prism is coated. Before cementing, with a metallic or dielectric layer having the desired reflecting properties, both in the percentage of reflection and the desired color. The absorption loss to the coating is minimal and transmission and reflection could be designed to 10%, 20%, 30%, 40%, 50%, etc.


Features:

●Low polarization dependence;

●Low power application;

●Not change the state of polarization of the incident beam.
