Polarizing Cube Beamsplitters (PBS Cubes)
Polarizing Cube Beamsplitters or PBS cube 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.
Hangzhou Shalom EO offers the custom PBS cubes upon customer's request, and the stocked modules are also available in fast delivery and low cost.
