This is a G063164000 31.5 mm diameter UVFS mounted double-convex lens, with a focal length of 60mm and uncoated surfaces. 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, with a base shape that is circular. The geometry of the lens is defined by a diameter of 31.5mm, a thickness at the edge of 2mm, and a thickness at the center of 6.2mm. The effective focal length (EFL) is 60mm, and the radii of curvature for the first and second surfaces are 59.996mm and -59.996mm respectively. The lens does not have any inner or outer radius.
The lens is made from UVFS material, specifically identified as "uvfs mal- 1965". The lens is designed to operate at a wavelength of 355nm. The lens does not have any coating applied to its surfaces.
The lens is currently in stock and available for purchase.
