Non-polarizing Beamsplitter Cube (NPBS) (NPBS-104)
Non-polarizing Beamsplitter Cube is formed by cementing a pair of precision high-tolerance right-angle prisms, one of which has its hypotenuse coated with a non-polarizing beamsplitting film; the low polarization dependence of the non-polarizing beamsplitting film keeps the transmission and reflection errors of the S polarization state and P polarization state within 5%, meaning they do not change the polarization state of the incident beam. We offer broadband and single-wavelength non-polarizing cube beamsplitters (NPBS); every face of the beamsplitter is coated with an anti-reflection coating to achieve the highest transmission efficiency within the appropriate wavelength range.

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.
