CSCH-40-550 40 x 40 mm N-BK7 Chromium Cube Beamsplitter; t=40mm 400-700nm
The CSCH-40-550 is a Cube Beamsplitter from OptoSigma, designed for use in the 400-700nm wavelength range. This beamsplitter is a cube-shaped optical element, with each side measuring 40mm, making it suitable for applications requiring a larger optical aperture.
The beamsplitter features a chromium coating on its hypotenuse faces, which is optimized for the 550nm wavelength. This coating provides a reflection of approximately 72% and a transmission of approximately 28%. The beamsplitter's other faces are coated with an ideal broadband anti-reflective (AR) coating, which further enhances its performance by reducing unwanted reflections.
The CSCH-40-550 is made from N-BK7 glass, a popular material for optical elements due to its excellent optical properties and wide transmission range. This beamsplitter is designed to fit into a 40mm cube, making it compatible with many optical systems that use this standard size.
