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.

What is the use of PBS?
PBS is vital in optics. In laser technology, it stabilizes polarization for precise processing. In optical communications, it separates or combines polarized light to reduce crosstalk and improve transmission efficiency. In optical instruments and display systems, it controls polarization to enhance signal detection and image quality. Its precise polarization - splitting feature makes it key for optimizing optical system performance.
