CSMH-20-550 20 x 20 mm 50:50 (R:T) N-BK7 Dielectric Half-Mirror Cube Beamsplitter; t=20mm 400-700nm

The CSMH-20-550 is a high-quality beamsplitter cube, designed and manufactured by OptoSigma. This beamsplitter is a crucial component in various optical systems, particularly where the division of an incident light beam into reflected and transmitted components is required.

The beamsplitter cube features a 20 x 20 mm cross-section, with each side measuring 20 mm, providing a substantial surface area for efficient light splitting. The beamsplitter is designed to operate with a 50:50 (R:T) ratio, meaning it reflects 50% of the incident light and transmits the remaining 50%. This ratio ensures balanced distribution of light, which is essential in many optical applications.

The CSMH-20-550 is made from N-BK7, a high-quality glass material known for its excellent optical properties. This material, often used in optical systems, ensures high light transmission and low absorption, making it an ideal choice for beamsplitters.

The beamsplitter's coating is another notable feature. Both the front and back surfaces are coated with ideal broadband AR, reducing reflection and enhancing transmission. The left and right surfaces also have the same coating for consistent performance. The hypotenuse faces 1 and 2 are coated with opt CSMH-550 and ideal broadband AR, respectively, ensuring optimal performance.

This beamsplitter cube is designed to operate within a wavelength range of 400-700 nm, making it suitable for a wide range of applications. The CSMH-20-550 is currently in stock and available for immediate use.
