63-825 9mm Dia. x 27mm FL; VIS-NIR Coated; UV Double-Convex Lens VIS-NIR 400-1000nm
The 63-825 is a high-quality double-convex lens, boasting a 9mm diameter and a 27mm focal length. This lens is sourced from the reputable optical vendor, Edmund Optics, and is available for purchase on their website. The lens features a VIS-NIR coating on both the front and back surfaces, enhancing its performance within the visible to near-infrared spectrum (400-1000nm).
The lens is constructed from fused silica, a material known for its excellent transparency and durability. The base shape is circular, and the lens exhibits a spherical geometry, with a center thickness of 2.5mm and an edge thickness of 1.66mm. The inner and outer radii are not specified, indicating that they are likely not a significant factor in the lens's performance or application.
The lens's effective focal length (EFL) is 27mm, and the back focal length (BFL) is 26.13mm. The first radius of curvature (R1) is 24.36mm, and the second radius of curvature (R2) is -24.36mm, indicating the lens's double-convex design.
