89-278 30mm Dia x 60mm FL; YAG-BBAR Coated; Double-Convex Lens YAG-BBAR 500-1100nm
The 89-278 is a high-quality double-convex lens, boasting a 30mm diameter and a focal length of 60mm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is currently in stock, as indicated by its weblink status.
The lens is constructed from the high-grade material, n-BK7 Schott, a borosilicate glass known for its excellent optical properties. The lens features a front and back coating of EDM YAGBBAR 500-1100, a broadband anti-reflection coating designed for use in the 500-1100nm wavelength range. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission and improving image quality.
The lens's geometry is meticulously designed, with an edge thickness of 1.26mm and a center thickness of 5mm. The radii of curvature for the first and second surfaces are 61.15mm and -61.15mm, respectively, resulting in a back focal length of 58.33mm. The lens's shape is spherical, a common and versatile design that provides excellent imaging capabilities.
