High-extinction-ratio polarizing beamsplitter prism
The polarizing beam-splitter prism divides incident unpolarized light into two orthogonal linearly polarized beams. Beam-splitter prisms are widely used in laser and illumination systems. High-extinction PBS with TP:TS>1000:1 is suitable for broadband use, while TP:TS>3000:1 is suitable for narrowband use.

尺寸公差: ±0.2 mm 面型 λ [@632.8 nm]: λ/4 @ 632.8 nm 表面质量: 60/40
The polarizing beam-splitter prism divides incident unpolarized light into two orthogonal linearly polarized beams. P-polarized light is fully transmitted, while S-polarized light is reflected at 45°, emerging at 90° to the P beam. The prism consists of two cemented, high-precision right-angle prisms, with a dielectric polarizing beam-splitter coating on the hypotenuse of one prism.

The nonpolarizing beamsplitter cube uses a multilayer interference coating on a right-angle prism hypotenuse, then cements two prisms into a cube. P and S components have similar splitting characteristics at specified wavelengths and reflection/transmission ratios while retaining their polarization states. Antireflection coatings cover the four external faces. Custom options include: (1) dimensions, (2) optical materials, (3) high-precision pentaprisms and (4) coating designs.

Conventional beam splitters separate or combine laser beams, while polarizing beam splitters separate or combine two orthogonally polarized laser beams. Beam-splitter performance depends primarily on the coating specifications.

A beamsplitter cube is made by cementing two precision right-angle prisms with a suitable interference coating on the hypotenuse. Coating absorption is minimal, and average transmission and reflection are close to 50%, although outputs are partly polarized. For polarization-sensitive applications, choose a polarizing beamsplitter (PBS) or nonpolarizing beamsplitter (NPBS) cube.
