洛匈偏光棱镜
Our UV Rochon prisms are made from high grade, a -BBO material with high birefringence and UV transparency. They can guarantee a wide transmission range, especially, suitable for UV applications.
Rochon prisms are beam splitting polarizers. The optic axis is parallel to the input beam for the first prism and perpendicular to the input beam for the second prism. This results in two orthogonal-polarized output beams. The ordinary ray is undeviated, the extraordinary ray deviated by an angle, theta, which is a function of wavelength and the prism angle.
