High Extinction Ratio Polarizing Beamsplitter Cubes

Material: K9 or other optical materials Clear Aperture Dimension: >90 % Parallelism [Up to the stated maximum; Actual specification according to customer requirements]: ≤1 ″

Material: K9 Clear Aperture Dimension: >90 % Surface Figure [Standard; 632.8nm; Per 25mm; Actual specification according to customer requirements]: λ/4

Material: BK7, fused silica, boron float glass, etc. Dimensional Tolerance: ±0.1 mm Surface Figure [633nm]: λ/4

These beamsplitter plates can be used in high-power laser systems. The two beams travel along different optical paths determined by the incidence angle and plate thickness.

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.

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.
