63-684 30mm Dia. x 30mm FL; VIS-NIR Coated; Double-Convex Lens VIS-NIR 400-1000nm
The 63-684 is a high-quality double-convex lens, boasting a 30mm diameter and a 30mm focal length. This lens is sourced from the reputable vendor, Edmund Optics, and is available for purchase on their official website, where it is currently in stock.
The lens is constructed from n-sf11 Schott, a material well-known for its excellent optical properties. It features a base shape of a circle, with a thickness of 1.43mm at the edge and 6.5mm at the center. The effective focal length (EFL) is 30mm, while the back focal length (BFL) is 28.12mm. The first radius of curvature (R1) is 45.61mm, and the second radius of curvature (R2) is -45.61mm.
The 63-684 lens is coated with edm visnir0sp2002000 on both the front and back surfaces. This specialized coating enhances its performance in the visible to near-infrared spectrum, specifically between 400nm and 1000nm. The lens's shape is spherical, ensuring excellent light transmission and minimal distortion.
