This is the G063031329 model from Qioptiq Photonics, a 22.4 mm diameter UVFS mounted double-convex lens designed for use with a focal length of 80mm at a wavelength of 1064nm. The lens is spherical in shape, featuring a symmetric convex-convex design with a base shape of a circle.
The lens's geometry is defined by its edge thickness of 1.7mm and center thickness of 3.3mm. The inner and outer radii are both zero, while the first and second radii are 78.298mm and -78.298mm respectively. The effective focal length (EFL) is 80mm.
The lens is made from UVFS material, specifically identified as "uvfs mal- 1965". It comes with a high-performance coating on both the front and back, specifically "qio hp nbar arhs-yag". This coating enhances the lens's durability and performance in its intended application.
