This is the G063163331, a 31.5 mm diameter UVFS mounted double-convex lens with an effective focal length (EFL) of 50mm. The lens is sourced from Qioptiq Photonics, a renowned vendor in the field of precision optics.
The lens is a spherical type, featuring a base shape of a circle. It has a convex-convex design, meaning both its surfaces are curved outwards. The lens's geometry includes a thickness of 2.2mm at the edge and 7.3mm at the center. The inner and outer radii are not specified, indicating that they are not a significant factor in this lens's specifications.
The lens is made from UVFS material with a Mal-1965 ID. It is designed to work with a wavelength of 355nm, making it suitable for applications that use this specific wavelength. The lens's coating is Qio AL RALVIS AOI 45 on both the front and back surfaces, which enhances its performance and durability.
