62-592 12.7mm Dia. x 15.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
This is a 12.7mm diameter, 15.0mm focal length plano-convex lens, specifically designed for the visible to near-infrared spectrum (VIS-NIR), covering the wavelength range of 400-1000nm. The lens is sourced from the reputable optical vendor, Edmund Optics.
The lens is made of the high-quality material n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties, including low dispersion and high transmission in the visible and near-infrared regions. The plano-convex geometry, with a 7.75mm radius of curvature, provides a large clear aperture and excellent image quality.
The lens features a broadband anti-reflection coating, denoted as 'edm visnir0sp2002000', on both the front and back surfaces. This coating is designed to reduce surface reflections and increase transmission, thereby enhancing the overall performance of the lens, especially in high-power applications.
The lens has a center thickness of 5.25mm and an edge thickness of 1.94mm, providing a robust and durable structure. The back focal length (BFL) is 11.53mm, which is crucial for determining the lens's placement in an optical system.
