Non-Polarizing Beamsplitter (NPBS)
Function of the Non-Polarizing Beamsplitter (NPBS): splits the incident light in a certain energy ratio (e.g. 50:50, 70:30, etc.), and the splitting ratio is independent of the polarization state. Operating Principle of the Non-Polarizing Beamsplitter Achieved by a neutral beam splitting coating (metallic or dielectric coating), the reflected and transmitted light contains all polarized components in a constant ratio. Splitting is more uniform for unpolarized light, e.g. 50:50 NPBS will reflect 50% of the energy and transmit 50% of the energy, regardless of polarization. What are the properties of the Non-Polarizing Beamsplitter? Polarization-independent: the spectral ratio remains stable over a wide range of wavelengths and angles of incidence. Low polarization sensitivity: reflected and transmitted light remains natural light (unpolarized).

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.
