Polarizing Beamsplitter (PBS)
Function of Polarizing Beamsplitter (PBS): splits the incident light into two orthogonally polarized beams (usually S-polarized and P-polarized) according to the polarization state of the light. Operating Principle: Using thin-film interference or birefringence effects (e.g., Wollaston prisms, Glen-Taylor prisms), incident light is decomposed into: S polarized light (perpendicularly polarized, reflected light) P polarized light (parallel polarization, transmitted light). The splitting ratio is highly dependent on the state of polarization, e.g. 50:50 PBS will separate unpolarized light by state of polarization rather than equally by energy.

Beamsplitter Beam Splitters 100optics
Material: K9 or ZF glass Dimensional Tolerance: ±0.2 mm Surface Quality: 60 / 40
A polarizing cube beamsplitter separates a randomly polarized beam into two orthogonal linearly polarized components: S polarization is reflected at 90 degrees, while P polarization is transmitted. Each consists of a pair of high-precision, high-tolerance right-angle prisms bonded with a dielectric coating on the hypotenuse of one prism. Baijing Optoelectronics offers high-quality beamsplitters.

Non-polarizing beamsplitter (NPBS) Beam Splitters 100optics
Material: K9 or ZF glass Dimensional Tolerance: ±0.2 mm Surface Quality: 60 / 40
Made by bonding two precision, high-tolerance right-angle prisms, with a metal-dielectric coating on the hypotenuse of one prism. The coating has low polarization dependence, keeping S- and P-polarized transmission and reflection within 6% of one another. The source states that the incident polarization is therefore unchanged.
