This is the G063320322 model from Qioptiq Photonics, a 22.4 mm diameter UVFS mounted double-convex lens designed for use in the 450-700nm wavelength range. The lens is spherical in shape, featuring a symmetric convex-convex design with a focal length (EFL) of 60mm.
The lens's geometry includes an edge thickness of 1.6mm and a center thickness of 3.7mm. The front and back surfaces of the lens are coated with Qioptiq's BBAR ARB2VISNBK7 coating, which is specifically designed to reduce reflection and increase transmission in the visible spectrum.
The lens is made from UVFS material, which is a type of fused silica known for its high transparency and excellent thermal stability. The lens's inner and outer radii are 0mm, indicating a uniform curvature across both surfaces.
