49-447 3mm Dia. x 3mm FL; VIS-NIR Coated; Double-Convex Lens VIS-NIR 400-1000nm
The 49-447 is a high-quality double-convex lens, sourced from the renowned optical components manufacturer, Edmund Optics. This lens, with a diameter of 3mm and a focal length of 3mm, is designed for use in the visible to near-infrared spectrum, spanning 400-1000nm.
The lens is crafted from n-SF5 Schott, a material known for its excellent optical properties, making it suitable for a wide range of applications. The double-convex geometry, with radii of curvature of 3.5mm for both the front and rear surfaces, ensures efficient light collection and focusing. The lens has an edge thickness of 1.64mm and a center thickness of 2.3mm, providing robustness and durability.
The 49-447 features a broadband anti-reflection coating, specifically the EDM VIS-NIR 0SP2002000 coating, on both the front and back surfaces. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission and improving overall system efficiency. The coating is designed to operate across the entire visible to near-infrared spectrum, making it a versatile choice for various applications.
