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 recommend that
Polarization Cube Beamsplitter or Non-Polarization Cube Beamsplitter.
