产品特点

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. Others T/R ratio is available upon request.

Beamsplitter penta prism is a penta prism glued with a wedge on a reflecting surface. It is used to divide an incident beam into two separate beams: Transmission(T) and reflection(R). The image is neither inverted nor reversed.
