This is the G052212322 model from Qioptiq Photonics, a 6 mm diameter UVFS mounted double-convex lens designed for use in the 450-700nm wavelength range. The lens is constructed with a symmetric convex-convex geometry, featuring a 5.012mm radius of curvature on both the front and back surfaces. This design results in an effective focal length (EFL) of 5mm.
The lens is made from UVFS material, specifically identified as "uvfs mal- 1965" in the item data. This material is known for its excellent transmittance and durability in ultraviolet and visible light spectra. The lens has a center thickness of 3mm and an edge thickness of 1mm, providing a robust structure while maintaining a compact form factor.
The G052212322 lens is equipped with broadband anti-reflection coatings on both the front and back surfaces. These coatings, identified as "qio bbar arb2visnbk7", are designed to minimize surface reflections and increase transmission efficiency across the entire 450-700nm wavelength range.
