Basic Parameters
We offer Rochon prisms in a variety of materials, including MgF2 crystals, a-BBO crystals, quartz crystals, and YVO4 crystals.
Rochon prisms are made by bonding two crystals with optical adhesive. They can convert incident unpolarized light into two orthogonally polarized beams, one propagating along the incident direction and the other deviating from the exit. They can operate over a wide range of wavelengths and have a relatively large field of view. Unlike other polarizers, the two beams output by the Rochon prism have very high polarization, with an Extinction Ratio greater than 10000:1 or greater than 100000:1. Rochon prisms are often used in spectral analysis systems, such as ellipsometers and spectrometers.

POLARIZING BEAM SPLITTER（PBS）
The polarization splitter prism is plated with a multilayer film structure on the inclined surface of the right Angle prism, and then glued into a cube structure. By taking advantage of the property that the transmission rate of P-polarized light is 1 and that of S-polarized light is less than 1 when the light incident at Brewster Angle, the P polarization component can be completely penetrated after the light passes through the multilayer film structure at Brewster Angle for many times. And most of the S polarization component is reflected. Note: Specific bands and extinction ratios can be customized according to customer requirements.
