G311338525 22.4 mm Dia. N-BK7 Double-Convex Lens; EFL=20mm 725-1050nm
This is a high-quality double-convex lens, model G311338525, manufactured by Qioptiq Photonics. It boasts a diameter of 22.4 mm and a thickness ranging from 1.6 mm at the edge to 8.8 mm at the center. The effective focal length (EFL) of this lens is 20 mm, making it suitable for a wide range of optical applications.
The lens is made from N-BK7, a popular glass type known for its excellent optical properties. This material is particularly suitable for use in the visible and near-infrared spectrum, with a wavelength of 587.6 nm. The lens features a double-convex geometry, with radii of curvature of 19.248 mm for both the front and back surfaces.
The lens is coated with a broadband anti-reflection coating, specifically the Qio Bbar Arb2nirnbk7 coating, on both the front and back surfaces. This coating is designed to reduce surface reflections and increase transmission, enhancing the overall performance of the lens.
