Plate Beam Splitter (BSPP)

Plate Beam Splitter Polarizers Diagram Plate Beam Splitter Polarizers Diagram 2

This polarizer splits light into two beams and transmits the p-polarized beam while reflects the s-polarized beam. The 45° angle of incidence makes mounting easier for optics comparing at Brewster’s angle of incidence. Due to the AR coating onto the surface, there is a high damage threshold that makes it useful for high optical power applications. Plate beam splitter polarizers are also used in photonics instrumentation, optical isolation and in many other applications. 

Plate Beam Splitter Polarizers are available with us in several wavelength ranges, desired wavelengths, shapes, sizes plus incidence angles and we can also make customer specifications.

Cube Beam Splitter (BSPC)

Cube Beam Splitter Polarizers Diagram Cube Beam Splitter Polarizers Diagram 2

Two right-angled prisms are put together by each hypotenuse respectively with the help of cement or optical contact to form a Cube Beam Splitter Polarizer. When an unpolarized light falls on the cube beam splitter polarizer, it separates input light into two polarization components and reflects the s-component of polarization.  Optical power tolerance is higher when the two prisms of the cube beam splitter are in optical contact thus usable for high power applications.  It is used in applications where the simplified mounting and system integration is an important aspect.  It is also used in the applications for imaging systems.

Our company offers Cube Beam Splitter Polarizer for a wide range of wavelengths (UV-NIR) in different dimensions for optimized performances.  A customized Cube Beam Splitter Polarizer can be manufactured based on our customer requirements.
