This is a 092-3115R-200 protected aluminium spherical plano-concave mirror, sourced from EKSMA Optics. The mirror has a diameter of 25.4 mm and a thickness of 6 mm at the edge. It is designed for use with a wavelength of 300 nm and features a UVFS protected aluminium coating on the front surface, identified as EKS 0015protal 3000.
The mirror's geometry is spherical, with a radius of curvature (R1) of -200 mm, resulting in a focal length (EFL) of -100 mm. This curvature and the plano surface on the other side make it a concave mirror. The mirror is designed to be used in optical systems that require a concave mirror with a specific focal length and radius of curvature.
The mirror's material, UVFS protected aluminium, is known for its high reflectivity in the ultraviolet region of the spectrum, making it suitable for use in UV optical systems. The UVFS protection ensures the longevity of the mirror by preventing oxidation and other forms of degradation.
