45-867 9mm Dia. x 13.5mm FL; VIS-NIR Coated; Double-Convex Lens VIS-NIR 400-1000nm
The 45-867 is a high-quality double-convex lens, sourced from the renowned optical components manufacturer, Edmund Optics. This lens boasts a 9mm diameter and a focal length of 13.5mm, making it suitable for a wide range of applications that require compact, high-performance optical elements.
The lens is crafted from Schott's n-BK7 glass, a material well-known for its excellent optical properties, including a high Abbe number and low dispersion. This ensures superior image quality and color fidelity, making the lens ideal for applications that demand high optical performance, such as imaging systems, beam shaping, and laser applications.
The 45-867 lens features a double-convex geometry, with radii of curvature of 13.46mm for the first surface and -13.46mm for the second surface. This geometry provides a large numerical aperture, enhancing the lens's light-gathering capability and improving its performance in low-light conditions. The lens has an edge thickness of 1.2mm and a center thickness of 2.75mm, ensuring robustness and durability.
The lens is coated with Edmund Optics' VIS-NIR coating (edm visnir0sp2002000), which provides excellent anti-reflection properties across the visible and near-infrared spectrum (400-1000nm). This coating reduces surface reflections, enhancing transmission and improving overall system performance.
