Beamsplitters are used to separate a light into two beams with designed T/R ratio, either plate or convenient cube shape. The Cube beamsplitter consist of two cemented right angle prisms with beamsplitting coating on the internal hypotenuse surface and all other four surfaces AR coated.

This cube beamsplitter use high efficiency dielectric coating design. The T/R ratio maybe be polarization dependent. If the polarization dependent is an issue to your application, please use our:
