This is the G063321331 model from Qioptiq Photonics, a 22.4 mm diameter UVFS mounted double-convex lens with an effective focal length (EFL) of 100mm. The lens is sourced from Qioptiq Photonics, a reputable vendor known for precision optics.
The lens is a spherical type, featuring a symmetric convex-convex design. The base shape is circular, and the geometry includes a thickness edge of 1.6mm and a thickness center of 2.9mm. The lens is mounted on UVFS material with the Mal-1965 ID.
The lens is designed to operate at a wavelength of 355nm and features a coating on both the front and back surfaces. The front coating is Qio AR AL RALVIS AOI 45, and the back coating is also Qio AR AL RALVIS AOI 45. This coating enhances the lens' performance and durability.
The lens's shape is spherical, and the radii of curvature are R1 = 100mm and R2 = -100mm. The inner and outer radii are both zero. The lens is currently in stock and available for purchase on the Qioptiq Photonics website.
