G311316525 22.4 mm Dia. N-BK7 Double-Convex Lens; EFL=60mm 725-1050nm
This is a G311316525 double-convex lens, sourced from Qioptiq Photonics, a renowned vendor in the field of precision optics. The lens boasts a diameter of 22.4 mm and a thickness of 2 mm at the edge, while the center thickness measures 4 mm. The effective focal length (EFL) of this lens is 60 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 62.643 mm for both the front and back surfaces. This geometry is designed to minimize spherical aberration and provide superior image quality.
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 improve transmission across the 725-1050 nm spectral range. The lens is currently in stock and available for immediate purchase, as indicated by its valid weblink status.
