Beamsplitter Penta Prism
Description
Beamsplitter penta prism assembly combines the transmitting/reflecting function of a beamsplitter with the 90 deg path bend associated with a penta prism (no inversion or reversion).
By adding a wedge and with partial reflective coating on first reflective surface(S1), Penta prism can be used as a beamsplitter. We supply beamsplitter penta prism with standard transmission/reflection (T/R) ratio of 20/80%, 50/50%. Other T/R ratios are available upon request.
