89-225 9mm Dia. x 18mm FL; YAG-BBAR Coated; Double-Convex Lens YAG-BBAR 500-1100nm
The 89-225 is a high-quality double-convex lens, sourced from the renowned optical vendor, Edmund Optics. This lens boasts a 9mm diameter and a focal length of 18mm, making it suitable for a wide range of optical applications.
The lens is constructed from Schott's n-BK7 glass, a popular material known for its excellent optical properties and versatility. The base shape of the lens is circular, and it features a double-convex geometry, with radii of curvature of 18.15mm and -18.15mm for the first and second surfaces, respectively. This geometry results in a back focal length of 17.12mm.
The 89-225 lens is coated with YAG-BBAR on both the front and back surfaces, within the wavelength range of 500-1100nm. This coating enhances the lens's performance by reducing reflection and increasing transmission, thereby improving overall system efficiency.
The lens is currently in stock and available for immediate purchase through the Edmund Optics website, as indicated by the "weblink status" field in the item data. This ensures that users can quickly acquire this component for their optical systems, without any unnecessary delays.
