CSMH-40-550 40 x 40 mm 50:50 (R:T) N-BK7 Dielectric Half-Mirror Cube Beamsplitter; t=40mm 400-700nm

The CSMH-40-550 is a 40 x 40 mm 50:50 (R:T) N-BK7 Dielectric Half-Mirror Cube Beamsplitter, designed and manufactured by OptoSigma. This beamsplitter is a crucial component in various optical systems, facilitating the division of incident light into reflected and transmitted components.

The beamsplitter boasts a robust and compact design, with dimensions of 40 mm x 40 mm x 40 mm, making it suitable for a wide range of applications. The CSMH-40-550 features a 50:50 reflection-to-transmission ratio, ensuring a balanced division of light. The reflection and transmission coefficients are 0.5 each, indicating that approximately half of the incident light will be reflected, while the other half will be transmitted through the beamsplitter.

The beamsplitter is constructed from N-BK7 Schott glass, a material known for its excellent optical properties and broadband transmission characteristics. The N-BK7 Schott glass ensures high-quality performance across a wide spectral range, from 400 nm to 700 nm.

The CSMH-40-550 is coated with Ideal Broadband AR on the front, back, left, and right surfaces, and Opt CSMH-550 on the hypotenuse 1 surface. These coatings enhance the beamsplitter's performance by reducing surface reflections and improving transmission. The Ideal Broadband AR coating provides high transmission and low reflection across a broad spectrum, while the Opt CSMH-550 coating is specifically optimized for the CSMH-550 beamsplitter.
