Non-Polarized Beam Splitter Prisms (also called depolarizing beam splitters) are used to maintain the ration of the original horizontal polarization and vertical polarization in the incident light after the beam splitting.The optical characteristics separation of P light and S light is less than 5%, the dispersion is low, and the color neutrality is good. The wavelengths cover 400-1600nm and are usually used in interferometers and various imaging instruments. Non-polarization depolarizing beamsplitters are utilized for randomly polarized light and are designed for applications where polarization effects are to be minimized. Hitronics produces both narrowband or broadband NPBS.
