G311323322 25.4 mm Dia. N-BK7 Double-Convex Lens; EFL=80mm 450-700nm

This is a G311323322 model lens from Qioptiq Photonics, a renowned provider of precision optics. The lens, which has a base shape of a circle, is a symmetric convex-convex (double-convex) type, designed for use in the spherical geometry category.

The lens has a diameter of 25.4 mm and a thickness at the edge of 5 mm, while the center thickness is 7 mm. The effective focal length (EFL) of this lens is 80 mm, and it is designed to work optimally with wavelengths within the 450-700 nm range. The lens is made from N-BK7, a popular glass type in the optical industry, known for its excellent optical properties and versatility.

The lens features anti-reflection coatings on both the front and back surfaces. These coatings, specifically the "qio bbar arb2visnbk7" type, are designed to reduce surface reflections and increase transmission, thereby enhancing the overall performance of the lens.

Please note that the inner and outer radii of this lens are 0, indicating that this lens does not have any special curvature or shape beyond its basic spherical design.
