CM254-200-G01 Dia:1 in Concave Mirror; f=200.0 mm Protected Aluminum

The CM254-200-G01 is a concave mirror offered by Thorlabs, a leading vendor in the optical components industry. This mirror, with a diameter of 25.4 millimeters, is designed for use in a variety of optical systems, particularly those requiring concave reflective elements.

The mirror's geometry is spherical, with a radius of curvature (R1) of -400 millimeters. This negative value indicates a concave shape, which is typical for concave mirrors. The effective focal length (EFL) is 200 millimeters, a common value for this type of mirror. This EFL is calculated as the absolute value of R1 divided by two, which is a standard formula for spherical mirrors.

The mirror's material is n-BK7 Schott, a high-quality borosilicate glass known for its excellent optical properties. This material is widely used in optical systems due to its low dispersion and high homogeneity.

The mirror features a protected aluminum coating, denoted as tho g01protalrefl12. This coating provides high reflectivity across a broad spectrum, typically from 350 to 1100 nanometers. The 'protected' nature of the coating refers to a transparent overcoat that shields the aluminum from oxidation and environmental degradation, ensuring long-term performance.

The mirror's edge thickness is 6.2 millimeters, while the center thickness is 6 millimeters. This thickness provides structural rigidity while minimizing weight, making the mirror suitable for various applications.
