Polarization Beamsplitter Cubes are an essential component for various optical applications, designed to efficiently split light beams based on polarization. These beamsplitters utilize two complementary prisms to achieve their function. The output beam that remains parallel to the input beam is p-polarized, while the orthogonal output beam is s-polarized. This precise separation of light beams makes them invaluable in scientific and industrial settings where polarization control is critical.

Crafted from high-quality BK-7 grade A optical glass, these beamsplitter cubes offer a dimension range from 3.2mm to 50.8mm, ensuring versatility for different optical setups. The meticulous construction allows for a dimensional tolerance of ±0.2mm and an angular tolerance of ±3 arc minutes, guaranteeing high precision in beam splitting tasks. The surface quality is maintained at a 60/40 scratch and dig specification, ensuring minimal interference in optical paths.

With a beam deviation of just 3 arc minutes and an extinction ratio greater than 100:1, these beamsplitters provide exceptional performance. The principal transmittance and reflectance values are optimized, with Tp>95% and Ts<1%, and Rs>99% and Rp<5%, respectively. The wavelength range spans from 226nm to 2300nm, making these beamsplitters suitable for a wide array of applications. Additionally, the polarization beamsplitter coating is applied on the hypotenuse, and an anti-reflective coating ensures R<0.25% per face for all four faces, enhancing the overall efficiency and reliability of the product.
