CSM33-20-550 20 x 20 mm 33:67 (R:T) N-BK7 Dielectric Cube Beamsplitter; t=20mm 400-700nm

The CSM33-20-550 is a high-quality beamsplitter cube designed for use in optical systems that require a 33:67 (R:T) split ratio at a central wavelength of 550nm. This beamsplitter is manufactured by OptoSigma, a leading vendor in the optical industry, and is available for purchase through their website.

This beamsplitter cube features a robust geometry, with each side measuring 20mm, making it suitable for a wide range of applications. The cube is made from N-BK7 Schott glass, a popular material known for its excellent optical properties and high damage threshold.

The CSM33-20-550 boasts a broadband anti-reflection coating on all surfaces, including the hypotenuse faces, which are specifically coated with an Opt CSM33-550 coating. This ensures minimal loss of light and high transmission rates, making it an ideal choice for applications that require high-precision optical splitting.

The beamsplitter's coating is designed to operate within a wavelength range of 400-700nm, making it versatile for use in various optical systems. The reflection and transmission ratios are carefully controlled to ensure a 33:67 (R:T) split, providing a reliable and consistent performance.
