45-158 9mm Dia. x 36mm FL; MgF2 Coated; Double-Convex Lens MgF2 400-700nm
The 45-158 is a high-quality double-convex lens, boasting a 9mm diameter and a focal length of 36mm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is available in stock for immediate use. The lens is made from the high-grade material, n-BK7 Schott, ensuring durability and excellent optical performance.
The lens features a double-convex geometry, with radii of curvature of 36.77mm and -36.77mm for the first and second surfaces, respectively. This geometry results in a back focal length of 35.15mm and an effective focal length of 36mm. The lens has a center thickness of 2.55mm and an edge thickness of 2mm, providing robustness and resistance to deformation.
The 45-158 lens is coated with MgF2 on both the front and back surfaces, following the standard EDM curve. This coating enhances the lens's performance in the visible spectrum, specifically between 400 and 700nm. The MgF2 coating reduces reflection, increases transmission, and improves overall image quality.
