This is a 091-0115R-2000 Protected Aluminium Spherical Plano-Concave Mirror, sourced from EKSMA Optics. The mirror has a diameter of 12.7 mm and a thickness of 6 mm at the edge. It is designed for use with a wavelength of 300 nm.
The mirror is made of N-BK7 Schott glass, a popular choice for its high homogeneity, low auto-fluorescence, and excellent transmission in the visible and near-infrared spectral ranges. The spherical shape of the mirror, with a radius of curvature of -2000 mm, allows for precise focusing of light. The effective focal length (EFL) of the mirror is -1000 mm, which is the distance from the mirror to the focus when the mirror is used as a convex mirror.
The mirror is coated with EKS 0015PROTAL 3000 on the front side. This coating provides high reflectivity and durability, making the mirror suitable for a wide range of applications. The protected aluminium coating ensures that the mirror maintains its reflective properties even when exposed to harsh environments.
