NPCH-10-7800 10 x 10 mm 50:50 (R:T) N-BK7 Non-polarizing Cube Beamsplitter; t=10mm 780nm

The NPCH-10-7800 is a non-polarizing cube beamsplitter offered by OptoSigma, designed for applications that require broadband performance and high damage threshold. This beamsplitter features a 10mm x 10mm aperture and is designed to operate at a 50:50 (R:T) split ratio for the 780nm wavelength.

The beamsplitter is constructed using N-BK7 Schott glass, a popular material for its excellent optical properties and availability. The N-BK7 substrate is coated with ideal broadband anti-reflection (AR) coatings on all surfaces, including the hypotenuse faces, to minimize reflection losses and improve transmission. The hypotenuse 1 surface is further coated with an OptoSigma-specific coating (NPCH-7800) to optimize performance at the specified 780nm wavelength.

The beamsplitter's cube shape ensures high mechanical stability and ease of integration into various optical systems. Its dimensions are 10mm x 10mm x 10mm, allowing for compact and efficient designs. The NPCH-10-7800 is currently in stock and available for purchase through the OptoSigma website, as indicated by its valid weblink status.
