89-217 6mm Dia. x 9mm FL; YAG-BBAR Coated; Double-Convex Lens YAG-BBAR 500-1100nm
The 89-217 is a high-quality double-convex lens, sourced from the renowned optical components manufacturer, Edmund Optics. This lens, with a 6mm diameter and a focal length of 9mm, is designed for use within the wavelength range of 500-1100nm, making it suitable for a wide range of optical applications.
The lens is constructed from Schott's n-BK7 glass, a popular material due to its excellent optical properties and high Abbe number. The base shape of the lens is circular, and it features a double-convex geometry, with radii of curvature of 8.91mm and -8.91mm for the first and second surfaces, respectively. This geometry results in a back focal length of 8.22mm.
The lens has a central thickness of 2.25mm and an edge thickness of 1.22mm, providing robustness and durability. The lens is coated with YAG-BBAR on both the front and back surfaces, enhancing its performance within the specified wavelength range. This coating reduces reflection and increases transmission, thereby improving the overall efficiency of the optical system in which it is used.
