This is the G063112000 31.5 mm Dia. UVFS Mounted Plano-Convex Lens, a high-quality optical component sourced from Qioptiq Photonics. This lens, designed for use in a variety of optical systems, features a plano-convex design with a 31.5 mm diameter and an effective focal length (EFL) of 50mm.
The lens is made from UVFS material, specifically identified as "UVFS mal- 1965" in the item data. This material is known for its transparency in the ultraviolet spectrum, making it suitable for applications that involve UV light. The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors.
The geometry of the lens is also noteworthy. It has a thickness of 2.1 mm at the edge and 7.5 mm at the center. The curvature of the convex side is defined by a radius of 25.483 mm. The lens does not have an inner or outer radius, indicating a simple, uniform curvature.
