Rochon Polarizers
Rochon polarizer is made of two birefringent prisms in optical contact with one another. The ordinary and extraordinary rays remain collinear throught the first prism. Upon entering the second prism, the ordinary rays do not experience a change in the refractive index and pass through the prism without deviation, while the extraordinary rays refract at the interface.
