Wollaston Polarizer

Wollaston Polarizer


Wollaston Polarizer is made of birefringence material prisms that are cemented together. The ordinary ray in the first half of the prism becomes the extraordinary ray in the second half. The Wollaston Polarizing beam splitter has approximately twice the deviation for the Rochon Polarizer.

Features

Cemented
Separate Ordinary and Extraordinary Beams at Certain Angle 
Suitable for Low Power Application and where the deviation is required
