This is the G063317400, a 22.4 mm diameter UVFS mounted double-convex lens with an effective focal length (EFL) of 30mm. The lens is sourced from Qioptiq Photonics, a renowned vendor in the field of precision optics.
The lens is of the spherical type, specifically a symmetric convex-convex lens, and is mounted on fused silica. The base shape is circular, with a thickness of 1.5mm at the edge and 6mm at the center. The inner and outer radii are both zero, and the radii of curvature are 29.007mm for both the first and second surfaces.
The lens is made from UVFS material with a Mal-1965 ID. It is designed to operate at a wavelength of 355nm and features a coating of Qio Silver RAGV 45 on both the front and back surfaces. This coating enhances the lens's performance and durability.
The lens is currently in stock and available for purchase. For more information, please refer to the vendor's website at https://www.qioptiq-shop.com/en/Precision-Optics/Singlets/Symmetric-Convex-Lenses/Symmetric-convex-lenses-mounted-fused-silica.html.
