CM750-056-M01 Dia:75 mm Concave Mirror; f=56.25 mm Protected Gold

The CM750-056-M01 is a concave mirror offered by Thorlabs with a diameter of 75 mm and a focal length of 56.25 mm. This mirror is designed to focus light to a single point, making it ideal for various applications such as beam shaping, focusing, and collimation.

The mirror is made from n-BK7 Schott glass, a popular material for optical elements due to its excellent optical properties and chemical resistance. The base shape of the mirror is circular, and it has a spherical geometry, which is the most common type of curved mirror due to its ease of manufacturing and versatility.

The mirror's thickness varies from 12 mm at the center to 18.4 mm at the edge, providing structural rigidity and minimizing potential distortions. The mirror's coating is tho m01protgoldrefl1 on the front side, which is a protected gold coating. This coating is known for its high reflectivity in the visible and near-infrared regions, making it suitable for a wide range of applications.

The mirror's effective focal length (EFL) is 56.25 mm, which is the distance from the mirror's surface to the point where the light rays converge. The radius of curvature (R1) is -112.5 mm, which is the distance from the mirror's surface to its center of curvature.
