This is a 092-3215R+300 25.4 mm Dia. UVFS Protected Aluminium Spherical Plano-Convex Mirror, with a center thickness of 6mm and a protective coating designed for a wavelength of 300nm. The mirror is sourced from EKSMA Optics, a reputable vendor in the optical components industry.
The mirror is a curved type, specifically convex, and is based on a circular geometry with a diameter of 25.4mm. The effective focal length (EFL) of this mirror is 150mm, and its radius of curvature (R1) is 300mm. The mirror is made of aluminium, a material known for its high reflectivity and durability.
The mirror's protective coating, UVFS, is designed to withstand harsh environments and maintain the mirror's performance. The coating on the front surface of the mirror is EKS 0015protal 3000, which is specifically designed for use with a 300nm wavelength.
This mirror is a spherical type, which means it has a single curvature. The spherical shape is a common choice in optical systems due to its ease of manufacturing and versatility.
