CSMH-30-405 30 x 30 mm 50:50 (R:T) N-BK7 Dielectric Half-Mirror Cube Beamsplitter; t=30mm 390-410nm

The CSMH-30-405 is a 30 x 30 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 N-BK7 Schott substrate, a popular choice in the optical industry due to its excellent optical properties and versatility. The geometry of the beamsplitter is a perfect cube, with each side measuring 30 mm, providing a compact and stable platform for beam splitting.

The physical data of the CSMH-30-405 indicates a 50:50 reflection-to-transmission ratio, ensuring a balanced division of the incident light. The wavelength of operation is 405 nm, making it suitable for applications in the blue region of the spectrum.

The beamsplitter features ideal broadband anti-reflective (AR) coatings on all surfaces, including the front, back, left, and right faces, as well as the hypotenuse faces. These coatings minimize unwanted reflections and improve the overall efficiency of the beamsplitter. The hypotenuse faces are specifically coated with an Opt CSMH-405 coating, further enhancing the beamsplitter's performance at the specified wavelength.
