PBS Polarized Beamsplitter

Polarizing Beamsplitter Cubes (PBS)

Polarizing Cube beamsplitters are constructed by cementing two precision right angle prism together with appropriate interference coating on the hypotenuse surface. The absorption loss to the coating is minimal transmission and reflection approach 50% (average) though output is partially polarized. If polarization sensitivity is critical to your application, we recommended that you select from our Polarization Cube Beamsplitter or Non-polarization Cube Beamsplitter.
