NPCH-20-6700 20 x 20 mm 50:50 (R:T) N-BK7 Non-polarizing Cube Beamsplitter; t=20mm 670nm

The NPCH-20-6700 is a non-polarizing cube beamsplitter offered by OptoSigma, designed for applications that require a 50:50 reflection-to-transmission ratio. This beamsplitter is crafted from high-quality N-BK7 glass from Schott, ensuring durability and reliability in various optical systems.

The beamsplitter features a 20 x 20 mm aperture, making it suitable for use in setups requiring a moderate amount of light. The 20 mm thickness of the cube ensures stability and reduces the risk of deformation due to external factors. The cube's design allows for easy integration into various optical systems, as it can be placed at any angle without affecting its performance.

The NPCH-20-6700 has been coated with ideal broadband anti-reflection (AR) coatings on all surfaces, including the hypotenuse faces. This coating reduces unwanted reflections and increases overall transmission, enhancing the performance of the beamsplitter. The hypotenuse faces have been coated with an OptoSigma-specific coating (NPCH-6700) for optimal performance at the specified wavelength of 670 nm.

This beamsplitter is available for purchase directly from the OptoSigma website, where users can find additional information and technical specifications. With its robust construction, reliable performance, and versatile design, the NPCH-20-6700 is an excellent choice for researchers and engineers seeking a high-quality non-polarizing cube beamsplitter for their optical systems.
