Polarization Beamsplitter Cubes are precision optical components designed to separate light beams based on their polarization states. These beamsplitters utilize two complementary prisms to achieve this separation, ensuring that the output beam parallel to the input is p-polarized, while the orthogonal output beam is s-polarized. This design is crucial for applications requiring precise control over light polarization.

The beamsplitters are crafted from high-quality BK-7 grade A optical glass, offering a robust and reliable solution for various optical systems. With a dimension range from 3.2mm to 50.8mm and a dimensional tolerance of ±0.2mm, these cubes are versatile enough to fit a wide array of setups. The angular tolerance of ±3 arc minutes and a surface quality of 60/40 ensure that the beamsplitters meet stringent optical standards.

These beamsplitters boast an impressive extinction ratio of >100:1, with principal transmittance values of Tp>95% and Ts<1%, and principal reflectance values of Rs>99% and Rp<5%. The wavelength range spans from 226nm to 2300nm, making them suitable for a broad spectrum 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, minimizing loss and maximizing efficiency.
