CM254-150-M01 Dia:1 in Concave Mirror; f=150.0 mm Protected Gold

The CM254-150-M01 is a concave mirror offered by Thorlabs, a leading vendor in the optical components industry. This mirror, with a base shape of a circle, has a diameter of 25.4 millimeters and a thickness that varies from 6.3 millimeters at the edge to 6 millimeters at the center.

The mirror's geometry includes an effective focal length (EFL) of 150 millimeters and a radius of curvature (R) of -300 millimeters, indicating a strongly curved surface. This curvature is consistent with the mirror's classification as a concave mirror, which is designed to reflect light rays towards a central point.

The mirror is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence. This material is suitable for a wide range of applications, including laser systems and interferometry.

The mirror's coating is a protected gold reflection coating, identified as tho m01protgoldrefl1. This coating is designed to provide high reflectivity in the visible spectrum, specifically at a wavelength of 588 nanometers. The 'protected' designation indicates that the coating is durable and resistant to environmental factors, ensuring longevity and reliability.
