This is the G063114331 model from Qioptiq Photonics, a 31.5 mm diameter Plano-Convex lens with a fused silica mount. The lens is designed for use with a center wavelength of 355 nm and features a front and back coating of Qio AL RALVIS AOI 45.
The lens's geometry is characterized by a 2 mm thickness at the edge and a 5.2 mm thickness at the center. It has an effective focal length (EFL) of 80 mm and a front radius (R1) of 40.681 mm. The lens's inner and outer radii are both 0, indicating a planar surface on the opposite side of the convex surface.
The lens is made from UVFS material, specifically UVFS MAL-1965, which is known for its excellent transmittance in the ultraviolet region. The lens is mounted, suggesting it is ready for immediate use in optical systems.
The vendor, Qioptiq Photonics, is a reputable supplier of precision optics, ensuring high-quality standards for this lens. The lens's web link indicates it is currently in stock, making it readily available for purchase and integration into optical systems.
