The CM508-100-G01 is a concave mirror offered by Thorlabs, a leading vendor in the optical industry. This mirror, with a base shape of a circle, has a diameter of 50.8 millimeters and a thickness that varies from 9 millimeters at the center to 10.6 millimeters at the edge.
The mirror's geometry is spherical, with a radius of curvature (R1) of -200 millimeters, indicating a concave shape. The effective focal length (EFL) is 100 millimeters, which is the distance from the mirror's center to the focal point.
This mirror is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties. The coating on the front surface is tho g01protalrefl12, a protected aluminum coating that provides high reflectivity.
The mirror is designed to operate at a wavelength of 588 nanometers. The 'protected' in the coating name refers to an overcoat that protects the aluminum from oxidation and tarnishing, ensuring the mirror maintains its performance over time.
