Polarizing Cube Beamsplitters split randomly polarized beams into two orthogonal, linearly, polarized components-S-polarized light is reflected at a 90deg. 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.
Currently. as coating technologies and assembly techniques have improved, so there are many types of polarizing beamsplitter cubes can be provided in the market. Dayoptics has own technology in providing two types of high precision polarizing beamsplitter cube. One is by using cemented method for PBS (as standard PBS), the other one is using optical bonding method for the interface of PBS (as high power PBS).
