Polarization Beamsplitter Cubes are an essential component for optical systems requiring precise light management. These beamsplitters utilize two complementary prisms to achieve their function. The design ensures that the output beam parallel to the input beam is p-polarized, while the orthogonal output beam is s-polarized. This polarization separation is crucial for applications demanding high precision and efficiency.

Crafted from BK-7 grade A optical glass, these beamsplitters are available in 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 minimal deviation. The surface quality is rated at 60/40 for scratch and dig, providing a high-quality finish suitable for demanding optical applications.

The beam deviation is kept within 3 arc minutes, and the extinction ratio exceeds 100:1, ensuring superior performance. The principal transmittance and reflectance values are optimized for efficiency, with Tp>95% and Ts<1%, and Rs>99% and Rp<5%, respectively. These beamsplitters cover a broad wavelength range from 226nm to 2300nm, making them versatile for various optical setups.

Each beamsplitter is coated with a polarization beamsplitter coating on the hypotenuse and an anti-reflective coating with R<0.25% per face for all four faces. This meticulous coating process enhances the beamsplitter's performance by minimizing reflection losses and maximizing transmission efficiency.
