Description
Polarizing Beamsplitters, often used in photonics instrumentation, split light by polarization state. Polarizing beamsplitters split monochromatic beam entering at zero degree into two orthogonal linearly polarized beam. S-polarized light is reflected at a 90 degree angle while P-polarized light is transmitted. Each beamsplitter consists of a pair of precision high tolerance right angle prisms cemented together with a dielectric coating on the hypotenuse of one of prisms. The losses of input beam of these products are minimized because of no absorption of dielectric coating. The other four surfaces of the cube are coated with narrowband multilayer antireflection coatings. Sherlan Optics’ anti-reflection coatings are designed for the Ultraviolet (UV), Visible, of Infrared (IR).
