CSCH-20-800 20 x 20 mm N-BK7 Chromium Cube Beamsplitter; t=20mm 750-850nm

The CSCH-20-800 is a Cube Beamsplitter from OptoSigma, designed for use in the 750-850nm wavelength range. This beamsplitter is a cube-shaped optical element, with each side measuring 20mm, making it suitable for applications requiring a substantial optical path.

The beamsplitter features a chromium coating on its hypotenuse faces, which is ideal for broadband applications. The front and back faces, as well as the left and right faces, are coated with an ideal broadband anti-reflective (AR) coating. This comprehensive coating ensures high transmission and low reflection across the specified wavelength range, enhancing the performance and efficiency of your optical system.

The CSCH-20-800 is made from N-BK7 Schott glass, a popular material for optical elements due to its excellent optical properties and wide transparency range. This beamsplitter has a reflection of 0.72 and a transmission of 0.28 at the specified wavelength, providing a good balance between these two parameters.
