Polarizing Beam Splitter Prism

An optical prism is a transparent object surrounded by two planes that intersect but are not parallel to each other. The most important parameters of a prism are angles and materials. Prisms are widely used in splitting, depolarization, polarization, image orientation, dual channel instruments, etc.

There are four main types of prisms based on the necessary function: dispersion prism, deflection or reflection prism, rotating prism, and offset prism. Deflection, offset, and rotating prisms are commonly used in imaging applications; diffusion prisms are designed as dispersive light sources and are not suitable for any application that requires high quality images.

SICUBE offers ODM and OEM high-end optical components, such as the PBS prism. We are the leading PBS prism manufacturer in China.

A polarizing beam splitter prism (PBS Prism) is an optical element used to separate horizontal polarization and vertical polarization of light.

The transmittance ratio of P light and S light is greater than 1000, and the transmittance of P light is more than 90%. It has the characteristics of a low stress / high extinction ratio, good imaging quality, and a small beam deflection angle. The wavelength range is 420-1600nm. It can be used for polarizing, detecting, and adjusting light intensity.


SICUBE's high precision optical prisms include Optical TIR/RTIR prisms, polarizing beam splitter(PBS) prisms, combination prisms, biometric prisms, AR prisms, and more. They are widely used in DLP projection, 3D cinema, fingerprint identification, 3D printing and scanning, AR display, and other fields. 


SICUBE optimized the polarizing beam splitter coating, backed by years of coating design experience and hardware strength. We produce double bonding, three bonding, four bonding, and five bonding PBS coating products. Our PBS prisms meet the needs of different industries such as laser interference, projection display, 3D cinema, and more.
