This is a 092-0115R-150 25.4 mm Dia. N-BK7 Protected Aluminium Spherical Plano-Concave Mirror, with a thickness of 6mm and a coating optimized for a wavelength of 300nm. The mirror is sourced from EKSMA Optics, a reputable vendor in the optical components industry.
The mirror is designed as a curved mirror with a concave shape, featuring a base shape of a circle. The diameter of this circle is 25.4mm, and the thickness of the mirror at the edge is 6mm. The effective focal length (EFL) of this mirror is -75mm, and the radius of curvature (R1) is -150mm, indicating a strongly curved mirror surface.
The mirror is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties and wide transmission range. This makes it suitable for various applications in the ultraviolet (UV) spectrum.
The mirror is coated with EKS 0015PROTAL 3000 on the front side. This coating is specifically designed to enhance the mirror's performance at a wavelength of 300nm, providing improved reflectivity and durability.
