The CM254-250-G01 is a concave mirror with a diameter of 1 inch (25.4 mm) and a focal length of 250.0 mm. This mirror is manufactured by Thorlabs, a leading vendor in the optical industry, and is available for purchase on their official website. The mirror's geometry is spherical, with a radius of curvature (R1) of -500 mm, which is typical for concave mirrors used in various optical systems.
The mirror's thickness varies from 6.2 mm at the edge to 6 mm at the center, providing structural rigidity and minimizing potential distortions caused by external forces. The mirror is made of BK7 glass, a high-quality borosilicate crown glass known for its excellent optical properties, including a low refractive index and low dispersion.
The CM254-250-G01 features a protected aluminum coating (tho g01protalrefl12) on the front surface, which provides high reflectivity in the visible spectrum, specifically at the wavelength of 588 nm. This coating is designed to withstand harsh environmental conditions and regular handling, ensuring the mirror's longevity and reliability in various applications.
