Polarized Beam Splitter Prism: 

Separate the horizontal polarization and vertical polarization of a beam of light, the ratio of the transmittance of P light to S light is greater than 1000, and the transmittance of P light is guaranteed to be above 90%. It has the characteristics of low stress, a high extinction ratio, deflection good imaging quality, and small beam angle. Wavelengths cover the 420-1600nm region. It can be used for polarization, polarization analysis, light intensity adjustment and other occasions.

Non-Polarized Beam Splitter Prism: 

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.
