4.5mm Diameter x 4.5mm FL VIS-NIR Coated Plano-Convex Lens by Edmund Optics
This 4.5mm diameter x 4.5mm FL plano-convex lens, sourced from the renowned optical vendor Edmund Optics, is a versatile and high-performing component designed for the visible to near-infrared spectrum (400-1000nm). Its plano-convex geometry, featuring a 3.61mm radius of curvature, offers excellent light-gathering capabilities and minimal optical aberrations, making it suitable for a wide range of applications.
The lens is made from the high-quality material n-lasf44 schott, ensuring durability and maintaining consistent optical properties over time. The lens features a center thickness of 2.59mm and an edge thickness of 1.8mm, providing a balance between compactness and robustness. The effective focal length (EFL) of 4.5mm further enhances its light-gathering capabilities and ensures high-quality imaging.
Both the front and back surfaces of the lens are coated with the advanced edm visnir0sp2002000 coating, which is specifically designed for the visible to near-infrared spectrum. This coating enhances the lens's transmission and reduces surface reflections, further improving its performance and ensuring optimal light transmission.
