Introduction

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.
