49-253 12mm Dia. x 24mm FL; UV-AR Coated; UV Double-Convex Lens UV-AR 250-425nm
The 49-253 is a UV-AR coated, double-convex lens with a diameter of 12mm and a focal length of 24mm. This lens, sourced from Edmund Optics, is designed for use within the UV spectrum, specifically between 250-425nm. The lens features a standard UV curve coating on both the front and back surfaces, providing enhanced protection and performance.
The lens's geometry includes an edge thickness of 1.39mm and a center thickness of 3.1mm. The front and back radii of curvature are 21.51mm and -21.51mm respectively, resulting in a back focal length of 22.92mm. The lens is made from fused silica, a material with a high transmission rate in the UV range.
This lens is a spherical design, which is a basic type of lens where both surfaces are parts of spheres. The spherical shape allows for a simple manufacturing process and provides good image quality, making it a versatile choice for various applications.
