产品说明

Rochon Polarizer 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.
