This is a 091-0215R+50 Protected Aluminium Spherical Plano-Convex Mirror, sourced from EKSMA Optics. The mirror has a circular base shape with a diameter of 12.7 mm and a thickness of 6 mm at the center. It is designed for use with a wavelength of 300 nm and features a front coating of EKS 0015PROTAL 3000.
The mirror's geometry includes a spherical shape with a radius of curvature (R1) of 50 mm, resulting in an effective focal length (EFL) of 25 mm. This curvature and the mirror's material, N-BK7 from Schott, make it suitable for a wide range of optical applications.
The mirror's protected aluminium coating ensures durability and resistance to environmental factors, making it a reliable choice for various applications. The coating also provides high reflectivity for the specified wavelength.
