Product Description
Wollaston Polarizer
Photonchina’s wollaston polarizer can separate an incident beam into two rays: extraordinary and ordinary ray with a deviation angle which is dependent on wavelength. Both rays are transmitted through the other surface.

ROCHON POLARIZERS
Rochon polarizer is made of two birefringent material prisms cemented or optical contacted together. The Rochon prism was invented by and is named after Abbé Alexis Marie Rochon. It is in many ways similar to the Wollaston prism, but the ordinary ray passes through the prism undeviated. Any separation angle can be designed according to request of customers.
Features
• Multiple Polarization Materials Available
• Ordinary Rays Pass Through Undeviated
• Extraordinary Rays Deviate

HIGH TRANSMSSION POLARIZER
High Transmission Glan Laser Polarizers is a special type of Glan Laser Polarizers. Its incidence angle is brewster angle cut which can greatly improve the transmission ray up to 98% in a wide range of wavelength without coating. The polarizer can be made from Calcite or YVO4 crystals. In order to get transmission of a wide range of wavelength, the polarizers are not recommended to use for large acceptance angle. It is typically used at the angle within+/-5®.
