Polarization Beamsplitter Cubes are an essential component for anyone looking to manage light polarization with precision and efficiency. These beamsplitters are 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 meticulous design allows for superior control over light polarization, making them invaluable in various optical applications.

Constructed from high-quality BK-7 grade A optical glass, these beamsplitters offer a dimension range from 3.2mm to 50.8mm, with a dimensional tolerance of ±0.2mm. The angular tolerance is maintained at ±3 arc minutes, ensuring precise alignment and performance. The surface quality is rated at 60/40 for scratch and dig, providing a clear and undistorted optical path. With a beam deviation of just 3 arc minutes and an extinction ratio greater than 100:1, these beamsplitters deliver exceptional performance.

The principal transmittance of these beamsplitters is Tp>95% and Ts<1%, while the principal reflectance is Rs>99% and Rp<5%. They are designed to operate effectively across a wavelength range of 226nm to 2300nm. The polarization beamsplitter coating is applied on the hypotenuse, and an AR coating ensures R<0.25% per face for all four faces, minimizing reflection losses and maximizing throughput.

For those requiring specific configurations, custom versions are available. Simply send your drawings or specifications, and a tailored quotation will be provided. Whether you need a standard or custom solution, these beamsplitters are designed to meet the highest standards of optical performance.
