89-120 3mm Dia. x 6mm FL; VIS-EXT Coated; Double-Convex Lens VIS-EXT 350-700nm
The 89-120 is a double-convex lens with a 3mm diameter and a 6mm focal length, sourced from the renowned optical component vendor, Edmund Optics. This lens is designed for use within the visible light spectrum, specifically between 350-700nm, making it suitable for a wide range of applications.
The lens is constructed from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This material ensures that the lens delivers sharp, clear images with minimal chromatic aberration.
The lens features a front and back coating of EDM VIS-EXT, a broadband anti-reflection coating specifically designed for use in the visible spectrum. This coating enhances the lens's light transmission capabilities, reducing unwanted reflections and improving overall image quality.
The geometry of the lens includes an edge thickness of 1.41mm and a center thickness of 1.8mm. The lens's effective focal length (EFL) is 6mm, and its back focal length (BFL) is 5.37mm. The first and second radii of curvature are 5.88mm and -5.88mm, respectively.
