CM508-050-E01 Dia:2 in Concave Mirror; 350-400nm; f=50 mm UV Broadband Dielectric

The CM508-050-E01 is a concave mirror with a diameter of 50.8 mm, manufactured by Thorlabs. This mirror is designed for use in the ultraviolet (UV) spectrum, specifically between 350 and 400 nm. The mirror's focal length is 50 mm, making it a versatile choice for a variety of optical applications.

The mirror is constructed from n-BK7 Schott glass, a material known for its excellent optical properties and high damage threshold. The base shape of the mirror is circular, with a thickness that varies from 12.2 mm at the edge to 9 mm at the center. This variation in thickness is designed to reduce optical aberrations and improve the mirror's performance.

The CM508-050-E01 features a spherical geometry, with a radius of curvature (R1) of -100 mm. This curvature, combined with the mirror's diameter and focal length, results in a high-quality, diffraction-limited optical surface.

The mirror is coated with a UV broadband dielectric coating, specifically the Thorlabs E01UVBB-D350400 coating. This coating is designed to enhance the mirror's reflectivity in the UV spectrum, ensuring optimal performance in its intended application range.

According to the vendor's website, the CM508-050-E01 is currently in stock, making it a readily available option for users in need of a high-quality UV concave mirror.
