CSMH-20-800 20 x 20 mm 50:50 (R:T) N-BK7 Dielectric Half-Mirror Cube Beamsplitter; t=20mm 750-850nm

The CSMH-20-800 is a dielectric half-mirror cube beamsplitter, 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 features a robust 20 x 20 mm N-BK7 (Schott) cube geometry, ensuring durability and precision. The cube's sides measure 20 mm each, making it suitable for applications requiring a larger aperture. The beamsplitter's coating is optimized for the 800 nm wavelength, with a reflection-to-transmission ratio of 50:50, providing a balanced split of the incident light.

The CSMH-20-800's coating comprises ideal broadband AR on the front, back, left, and right surfaces, and a specialized coating (Opt CSMH-800) on the hypotenuse 1 surface. The hypotenuse 2 surface is coated with ideal broadband AR, ensuring minimal reflection and loss of light. This careful coating design enhances the beamsplitter's performance across the specified wavelength range.
