This is the G063163400 31.5 mm Dia. UVFS Mounted Double-Convex Lens, a high-quality optical component sourced from Qioptiq Photonics. This lens, with its symmetrical convex-convex design, is mounted on fused silica (UVFS) and has a diameter of 31.5 mm.
The lens features an effective focal length (EFL) of 50mm, making it suitable for a wide range of optical applications. The geometry of the lens includes a thickness of 2.2mm at the edge and 7.3mm at the center, providing a robust and durable structure. The radii of curvature for the first and second surfaces are 49.581mm and -49.581mm respectively, contributing to its double-convex design.
The lens is made from a material identified as "uvfs mal- 1965", and it is coated with Qioptiq's proprietary silver coating (RAGV 45) on both the front and back surfaces. This coating enhances the lens's performance in the 355nm wavelength range.
The lens's shape is spherical, a common choice for its ease of manufacturing and versatility in various optical systems.
