NPCH-20-5320 20 x 20 mm 50:50 (R:T) N-BK7 Non-polarizing Cube Beamsplitter; t=20mm 532nm

The NPCH-20-5320 is a non-polarizing cube beamsplitter offered by OptoSigma, designed for use in various optical systems. This beamsplitter features a 20 x 20 mm aperture and is designed to operate at a wavelength of 532 nm, making it suitable for applications involving green light.

The beamsplitter is constructed from N-BK7 glass, a popular material in optical systems due to its excellent optical properties and wide transparency range. The beamsplitter is designed to reflect 50% of the incident light and transmit 50%, offering a balanced split of the incoming beam.

The NPCH-20-5320 features broadband anti-reflection coatings on all surfaces, including the hypotenuse faces. These coatings are designed to minimize reflection losses and improve transmission, ensuring optimal performance in your optical system. The hypotenuse faces are coated with an OptoSigma-specific coating, denoted as "opt npch-5320", further enhancing the beamsplitter's performance at the specified wavelength.

With a cubic geometry and a 20 mm edge length, this beamsplitter is designed to fit into standard 20 mm optical systems, making it a versatile component for a wide range of applications. The beamsplitter's cube shape also provides excellent stability and durability, ensuring long-lasting performance.
