Wollaston Polarizer, Rochon Polarizer, Wollaston Prism, BBO/Calcite/YVO4/Quartz
Description
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.

Features
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
