This is the G052213329 model from Qioptiq Photonics, a 10 mm diameter UVFS mounted double-convex lens designed for use with a 1064nm wavelength. The lens is part of Qioptiq's Precision Optics range, specifically the Symmetric Convex Lenses category, and is mounted on fused silica.
The lens features a double-convex geometry, meaning it has two spherical surfaces that curve outwards. The first surface, or the front surface, has a radius of curvature (R1) of 9.578, while the second surface, or the back surface, has a radius of curvature (R2) of -9.578. This geometry gives the lens an effective focal length (EFL) of 10mm.
The lens has a thickness of 1.2mm at the edge and 4mm at the center. The inner and outer radii are both 0, indicating that the lens does not have any additional shaping or curvature beyond its spherical surfaces.
The lens is made from UVFS material, specifically identified as "uvfs mal- 1965" in the item data. It is coated with Qio HP Nbar Arhs-Yag on both the front and back surfaces, which is designed to enhance its performance with 1064nm wavelengths.
