Rochon Polarizer is the earliest polarizer, which is made of two birefringence material prisms that are cemented together. This type polarizer separates incident beam into ordinary ray and extra-ordinary ray like Wollaston Polarizer, but the extra-ordinary ray is straight transmitted through, while ordinary is transmitted with a deviation angle.
