A Polarizing Beam Splitter (PBS) Cube Prism operates on the principle of polarization. It consists of two right-angle prisms cemented together with a dielectric coating at the hypotenuse. This coating selectively transmits and reflects light based on its polarization state. S-polarized light is reflected at a 90-degree angle, while P-polarized light passes straight through. This separation of light into two polarized beams makes PBS cubes essential in various optical applications, including laser systems, quantum computing, and telecommunications.
