Rochon Polarizing Prisms

Rochon polarizing prisms are made of two birefringent α-BBO prisms, which are cemented together. The first prism (cut parallel to the optic axis) receives the light, while the second (facing the optic axis at right angles) transmits the ordinary ray without deviation, but the extraordinary ray is deflected.


Rochon prisms can be used to produce plane-polarized light. and it can also be used with ultraviolet light. Prisms with non-standard separation angles can be designed upon request for your specific wavelength.
