Discover the precision and reliability of our Polarization Beamsplitter Cubes, expertly crafted to meet the highest standards of optical performance. These beamsplitters are ingeniously designed 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 guarantees superior performance in a wide range of optical applications.

Our beamsplitter cubes are constructed from BK-7 grade A optical glass, renowned for its clarity and durability. With a dimension range from 3.2mm to 50.8mm, these cubes offer flexibility for various optical setups. The dimensional tolerance of ±0.2mm and angular tolerance of ±3 arc minutes ensure precise alignment and integration into your optical systems. Surface quality is maintained at a high standard with a 60/40 scratch and dig specification, providing clear and undistorted light transmission.

Engineered for optimal performance, these beamsplitters feature a beam deviation of just 3 arc minutes and an impressive extinction ratio of greater than 100:1. The principal transmittance and reflectance values are optimized for maximum efficiency, with Tp>95% and Ts<1%, and Rs>99% and Rp<5%, respectively. The polarization beamsplitter coating on the hypotenuse and AR coating with R<0.25% per face for four faces further enhance the optical performance across a broad wavelength range of 226nm to 2300nm.

We offer a variety of models to suit your specific needs, with sizes ranging from 5x5x5mm to 20x20x20mm. Whether you require narrow band wavelengths such as 488nm, 514nm, or 1064nm, or broad band ranges, we have the right solution for you. For orders of 10 pieces or more, we provide attractive volume discounts, and next day shipping is available for most wavelengths. If you have unique requirements, we are pleased to offer custom solutions tailored to your specifications.
