Nonpolarizing Cube Beamsplitter NPB0-202
Non-polarizing Beamsplitter Cube consists of a pair of precision high tolerance right angle prisms cemented together with a metallic-dielectric coating on the hypotenuse of one of the prisms. The low polarization dependence of the metallic-dielectric coating allows the transmission and reflection for S- and P- polarization states to be within 5% of each other. This means that they will not change the state of polarization of the incident beam. We offer both broadband and single wavelength non-polarizing cube beamsplitters (NPBS). An antireflective coating has beem applied to each face of the beamsplitter in order to produce maximum transmission efficiency for the appropriate wavelength range. Note: Other sizes, wavelength are available upon request.

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.
