Polarization Beamsplitter Cubes are an essential component for precision optical applications, offering unparalleled performance in separating polarized light. These beamsplitters are expertly crafted using two complementary prisms, ensuring that the output beam parallel to the input beam is p-polarized, while the orthogonal output beam is s-polarized. This design provides a high degree of polarization separation, making them ideal for a variety of scientific and industrial applications.

Constructed from high-quality BK-7 grade A optical glass, these beamsplitter cubes are available in a range of dimensions from 3.2mm to 50.8mm, with precise dimensional tolerances of ±0.2mm. The angular tolerance of ±3 arc minutes ensures accurate beam alignment, while the surface quality of 60/40 guarantees minimal optical distortion. With a beam deviation of just 3 arc minutes and an extinction ratio greater than 100:1, these cubes deliver exceptional optical performance.

The polarization beamsplitter coating is applied to the hypotenuse, enhancing the principal transmittance (Tp>95% and Ts<1%) and reflectance (Rs>99% and Rp<5%) across a broad wavelength range of 226nm to 2300nm. Additionally, an anti-reflective coating with R<0.25% per face for all four faces minimizes unwanted reflections, ensuring maximum efficiency and clarity in optical systems.

For those seeking tailored solutions, custom versions of these beamsplitters are available. Simply provide your drawings or specifications, and a quotation will be prepared to meet your specific needs. Whether for research, development, or production, these polarization beamsplitter cubes offer a reliable and high-performance solution for your optical requirements.
