This is the G052121322 model from Qioptiq Photonics, a 10 mm diameter Plano-Convex lens with a mounted fused silica. The lens is designed for use within the ultraviolet to near-infrared spectrum, specifically between 450 and 700 nanometers.
The lens's geometry is characterized by a convex shape on one side, with a 7.499 mm radius. The lens's edge thickness is 1 mm, while the center thickness is 2.9 mm. The effective focal length (EFL) of this lens is 15 mm.
The lens is made from UVFS material, identified as "uvfs mal- 1965". It features a broadband anti-reflection coating on both the front and back surfaces, specifically Qio Bbar Arb2visnbk7. This coating is designed to reduce surface reflections and increase transmission, thereby enhancing the overall performance of the lens.
The lens's shape is spherical, a common choice for its simplicity and wide range of applications. The lens is mounted, which adds to its convenience and ease of use.
