G311331525 31.5 mm Dia. N-SK2 Double-Convex Lens; EFL=30mm 725-1050nm
This is the G311331525, a 31.5 mm diameter double-convex lens made from N-SK2 Schott glass. The lens features a high refractive index and low dispersion, making it an excellent choice for a wide range of optical applications. The lens has an effective focal length (EFL) of 30mm, designed to operate within the wavelength range of 725-1050nm.
The lens's geometry includes a 2mm thickness at the edge and a 9.5mm thickness at the center, with a clear aperture of 31.5mm. The front and back radii of curvature are 34.721mm and -34.721mm, respectively, providing a symmetrical convex-convex shape. The lens is unmounted, offering flexibility for integration into various optical systems.
The G311331525 lens comes with a broadband anti-reflection coating (BBAR) on both the front and back surfaces, specifically the Qio Bbar Arb2nirnbk7 coating. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, thereby minimizing light loss.
This lens is available from Qioptiq Photonics, a renowned vendor in the precision optics industry. The item data indicates that the product is in stock, ensuring quick delivery for your optical project needs.
