The CM254-019-M01 is a concave mirror offered by Thorlabs, a leading global manufacturer of photonics components. This mirror, with a diameter of 25.4 mm, is designed for use in optical systems that require a curved mirror with a high degree of precision.
The mirror's concave shape, defined by a radius of curvature (R1) of -38 mm, provides a focal length (EFL) of 19 mm. This means that light rays parallel to the mirror's axis will converge at a point 19 mm away from the mirror. The mirror's thickness varies from 8.1 mm at the edge to 6 mm at the center, providing structural rigidity while minimizing weight.
The mirror is made from N-BK7 Schott glass, a popular choice in optical systems due to its excellent optical properties and high Abbe number. This makes it an ideal material for applications that require high optical quality and low dispersion.
The mirror's front surface is coated with tho m01protgoldrefl1, a protected gold coating. This coating provides high reflectivity in the visible spectrum, making it suitable for applications that use light in the 588 nm wavelength range. The gold coating is also highly resistant to oxidation and corrosion, ensuring long-term performance and durability.
