48-260 50mm Dia. x 50mm FL; VIS 0deg Coated; Double-Convex Lens VIS 0deg 425-675nm
The 48-260 is a high-quality Double-Convex Lens, sourced from the renowned optical vendor, Edmund Optics. This lens boasts a 50mm diameter and a focal length of 50mm, making it a versatile choice for various optical applications.
The lens is constructed from n-sf11 Schott, a high-index glass material known for its excellent optical properties. The base shape of the lens is circular, and it features a double-convex geometry, with radii of curvature R1 and R2 measured at 74.78mm and -74.78mm respectively. This geometry contributes to the lens's high optical power and excellent imaging capabilities.
The 48-260 lens has a thickness of 7.39mm at the edge and 16mm at the center, providing robustness and durability. The effective focal length (EFL) is 50mm, and the back focal length (BFL) is 45.3mm, ensuring optimal focus and alignment in your optical system.
The lens is coated with the EDM VIS-0 standard curve on both the front and back surfaces. This coating enhances the lens's transmission in the visible spectrum, specifically between 425-675nm, making it ideal for applications such as microscopy, beam shaping, and imaging systems.
