CM254-075-M01 Dia:1 in Concave Mirror; f=75.0 mm Protected Gold

The CM254-075-M01 is a concave mirror with a diameter of 1 inch (25.4 mm) and a focal length of 75.0 mm, manufactured by Thorlabs. This mirror is made of n-BK7 Schott glass, a common material in optical systems due to its excellent homogeneity and low optical dispersion.

The mirror's geometry includes a thickness of 6.5 mm at the edge and 6 mm at the center, providing structural rigidity and resistance to deformation. The spherical shape of the mirror ensures a consistent curvature, which is crucial for focusing or collimating light.

The mirror's coating is a protected gold reflection (tho m01protgoldrefl1), which is highly reflective across a wide range of wavelengths, including the visible spectrum. This coating is also resistant to oxidation and tarnishing, ensuring long-term performance and durability.
