49-247 6mm Dia. x 9mm FL; UV-AR Coated; UV Double-Convex Lens UV-AR 250-425nm
This 49-247 model is a UV-AR coated, double-convex lens, sourced from the reputable vendor, Edmund Optics. The lens boasts a 6mm diameter and a 9mm focal length, making it suitable for a wide range of optical applications.
The lens is crafted from fused silica, a material known for its excellent transparency and resistance to thermal shock. The base shape is circular, and the lens features a spherical geometry, with an inner radius of 0 and an outer radius of 0. The lens has a center thickness of 2.7mm and an edge thickness of 1.5mm, providing a solid structure for various optical setups.
The lens is coated with a UV-AR coating on both the front and back surfaces, following the standard curve. This coating enhances the lens's performance in the UV region, specifically between 250-425nm, by reducing surface reflections and increasing transmission. The effective focal length (EFL) of the lens is 9mm, and the back focal length (BFL) is 8.02mm, offering versatility in optical design.
