格蘭-泰勒棱鏡
Each polarizer is comprised of two mounted air-spaced same birefringent material prisms which are available uncoated or with a broadband antireflection coating. The extraordinary rays are transmitted through both prisms while the ordinary rays are reflected off the hypotenuse and transmitted out the escape window (Cutting angle close to Brewster's Angle for normal incidence beam), allowing the component to be used as a polarizing beamsplitter. They can be used in Q-switched laser cavities and other multiple pass applications. The polarizers are offered with broadband AR coatings for the visible and NIR regions or a special V-coating for 1064 nm.
