45-927 6mm Dia. x -6mm FL; VIS-NIR Coated; Double-Concave Lens 400-1000nm
The 45-927 is a high-quality double-concave lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 6mm and a focal length of -6mm, is designed for use in the visible to near-infrared spectrum, making it suitable for a wide range of optical applications.
The lens is crafted from n-SF11 Schott, a high-index glass material known for its excellent optical properties. The double-concave geometry, characterized by radii of curvature of -9.74mm and 9.74mm, ensures precise light bending and focusing. The lens has an edge thickness of 2.29mm and a center thickness of 1.5mm, providing robustness and durability.
The lens features a VIS-NIR coating, denoted as edm visnir0sp2002000, on both the front and back surfaces. This coating is designed to enhance the lens's performance in the visible to near-infrared spectrum, reducing surface reflections and improving transmission.
