This is the G311716331 model from Qioptiq Photonics, a 31.5 mm diameter double-convex lens made of UVFS material with an effective focal length (EFL) of 100mm. The lens features a base shape of a circle and is designed for use in spherical applications.
The lens has a thickness of 2mm at the edge and 4.5mm at the center, providing a robust structure and optimal performance. The front and back surfaces of the lens are coated with Qio AL RALVIS AOI 45, enhancing its durability and functionality in the ultraviolet range, specifically at a wavelength of 355nm.
The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm, indicating a symmetrical design. The lens's curvature is defined by a first radius (r1) of 101.092mm and a second radius (r2) of -101.092mm, which contributes to its double-convex shape.
