Beamsplitter Penta Prism

Beamsplitter Penta Prism

By adding a wedge and with partial reflective coating on first reflective surface,Penta Prism can be used as Beamsplitter.We supply Beamsplitter Penta Prism with standard Transmission/reflection (T/R) ratio of 20/80,50/50.Other T/R ratio is available upon request.
