PBS
A polarizing beamsplitter prism can split incident unpolarized light into two perpendicular linearly polarized beams. The P-polarized light passes through completely, while the S-polarized light is reflected at a 45-degree angle, exiting at 90 degrees to the P beam. This polarizing beamsplitter prism is made by cementing a pair of high-precision right-angle prisms, with a polarizing beamsplitter dielectric coating on the hypotenuse of one prism. Taopu offers a variety of PBS prism specifications for your selection.

Overview
Specifications
| Parameter | Value |
|---|---|
| Optical Material | Standard materials: N-SF2, N-SF57, H-ZF52; other optical glass available on request |
| Cube Size | Size range: 4mm ~ 80mm; common specifications: 10mm, 12.7mm, 20mm, 25.4mm, 30mm, etc. |
| Surface Flatness | Less than 1/4λ @ 632.8nm (surface figure accuracy referenced to the He-Ne laser wavelength; the smaller the value, the better the surface figure) |
| Beam Deflection Angle | Less than 3 arcminutes (arc min, an angular unit, 1°=60 arcmin; the smaller the value, the more precise the beam direction control) |
| Applicable Wavelength | Standard band: 420-680 nm (visible band); other bands available on request |
| Transmission / Reflection Performance | Tp (p-polarization transmittance) >95%, Rs (s-polarization reflectance) >99.5% |
| AR Coating (Anti-Reflection Coating) | At 0° angle of incidence (AOI), residual reflectance R < 0.35%, effectively reducing interface reflection loss |

A polarizing beamsplitter prism is formed by cementing a pair of high-precision right-angle prisms. A polarizing beamsplitting dielectric coating is deposited on the hypotenuse of one of the prisms, and an anti-reflection coating is deposited on the outer surface. It can split incident unpolarized light into two beams of perpendicular linearly polarized light, in which the P-polarized light passes through completely, and the S-polarized light is reflected at 45 degrees, with the exit direction forming a 90-degree angle with the P-polarized light.
