CM254-500-M01 Dia:1 in Concave Mirror; f=500.0 mm Protected Gold

The CM254-500-M01 is a concave mirror with a diameter of 1 inch, manufactured by Thorlabs. This mirror is designed with a focal length of 500.0 mm and a protected gold coating on the front surface, making it suitable for a wide range of optical applications.

The mirror is made from n-BK7 Schott glass, a popular material due to its excellent optical properties and high damage threshold. The base shape of the mirror is circular, with a thickness of 6.1 mm at the edge and 6 mm at the center. This ensures the mirror's durability and stability, making it suitable for use in various optical systems.

The concave shape of the mirror, with a radius of curvature of -1000 mm, allows for the convergence of light rays to a single point, making it ideal for focusing applications. The protected gold coating on the front surface provides high reflectivity in the visible and near-infrared regions of the spectrum, typically around 588 nm. This coating is also resistant to oxidation and tarnishing, ensuring long-term performance and reliability.
