Wollaston Polarizers：
Wollston polarizer is made of two birefringent prisms that are cemented together, such that their optical axes are perpendicular. As light passes through the polarizer, a symmetric deviation bwtween the ordinary and extraordinary beams is created. The resulting beams are of orthoganal linear polarization states and have equal intensity and a large angular deviation. Users have access to both the ordinary and extraordinary rays, making them ideal for laboratory experiments.
