33-416 40mm Dia. x 200mm FL; VIS-NIR Coated; Double-Convex Lens VIS-NIR 400-1000nm
The 33-416 is a high-quality double-convex lens, sourced from the reputable vendor Edmund Optics. This lens boasts a 40mm diameter and a focal length of 200mm, making it suitable for a wide range of applications. The lens is constructed from the high-performance material N-BK7 Schott, ensuring excellent optical properties and durability.
The lens features a double-convex geometry, with radii of curvature of 205.35mm and -205.35mm for the first and second surfaces, respectively. This geometry results in a beneficial effect on the beam's divergence, making it an excellent choice for focusing or collimating light. The lens has an edge thickness of 6.05mm and a center thickness of 8mm, providing robustness and resistance to damage.
The 33-416 lens is coated with a VIS-NIR coating, specifically the EDM VISNIR0SP2002000 coating on both the front and back surfaces. This coating is designed for the visible and near-infrared spectrum, spanning 400-1000nm. It enhances the lens's performance by reducing surface reflections, thereby increasing transmission and improving overall system efficiency.
