63-673 15mm Dia. x 45mm FL; VIS-NIR Coated; Double-Convex Lens VIS-NIR 400-1000nm
The 63-673 is a high-quality double-convex lens, 15mm in diameter and 45mm in focal length, sourced from the renowned optical vendor, Edmund Optics. This lens is designed for use within the visible to near-infrared spectrum, spanning 400 to 1000nm, making it suitable for a wide range of optical applications.
The lens geometry features a center thickness of 3mm and an edge thickness of 1.77mm, with a base shape of a circle. The front and back radii of curvature are 45.99mm and -45.99mm respectively, contributing to a back focal length of 44mm. The lens is made from the high-quality material n-BK7 Schott, ensuring excellent optical performance.
The lens is coated with a VIS-NIR coating, specifically the EDM VISNIR0SP2002000 coating, on both the front and back surfaces. This coating enhances the lens's performance within the specified wavelength range, reducing surface reflections and increasing transmission.
