This is a 092-0215R+300 Protected Aluminium Spherical Plano-Convex Mirror, sourced from EKSMA Optics. The mirror has a diameter of 25.4 mm and a center thickness of 6 mm, making it a compact and robust option for various optical applications.
The mirror is made of N-BK7 Schott glass, a popular material known for its excellent optical properties and high damage threshold. This makes the mirror suitable for use in high-power laser applications.
The mirror's curvature is spherical, with a radius of curvature (R1) of 300 mm. This curvature, combined with the mirror's diameter, gives an effective focal length (EFL) of 150 mm. This makes the mirror ideal for focusing or collimating light in various optical systems.
The mirror is coated with EKS 0015PROTAL 3000 on the front side. This coating is designed to enhance the mirror's reflectivity at a wavelength of 300 nm, making it suitable for use in ultraviolet (UV) applications.
