Polarization Beamsplitter Cubes are an essential component in optical systems, designed to split a beam of light into two separate beams with orthogonal polarizations. These beamsplitters are crafted using two complementary prisms, ensuring that the output beam parallel to the input is p-polarized, while the orthogonal output beam is s-polarized. This precise separation of polarizations makes them invaluable in various scientific and industrial applications where light manipulation is crucial.

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 a dimensional tolerance of ±0.2mm. The angular tolerance is maintained at ±3 arc minutes, ensuring high precision in beam deviation, which is also kept within 3 arc minutes. The surface quality is rated at 60/40 for scratch and dig, reflecting the meticulous craftsmanship involved in their production.

The polarization beamsplitter coating is applied on the hypotenuse, enhancing the device's efficiency. The principal transmittance and reflectance are optimized, with Tp>95% and Ts<1% for transmittance, and Rs>99% and Rp<5% for reflectance. These specifications ensure that the beamsplitter performs exceptionally well across a broad wavelength range of 226nm to 2300nm. Additionally, an anti-reflective coating is applied to four faces, with reflectance kept below 0.25% per face, further improving optical performance.
