Custom Beamsplitter Prisms

Beamsplitter prisms are optical components used to split or combine light beams. They are commonly made by cementing two right angle prisms together with a beamsplitting coating applied to the hypotenuse surface. The coating determines the reflection and transmission ratio.

Beamsplitter prisms are widely used in imaging systems, laser systems, interferometers, microscopes, optical instruments and scientific research applications.
