49-246 6mm Dia. x 6mm FL; UV-AR Coated; UV Double-Convex Lens UV-AR 250-425nm
This 6mm diameter x 6mm focal length UV-AR coated double-convex lens, sourced from Edmund Optics, is a high-quality optical component designed for applications within the UV spectrum. The lens features a standard curve coating on both the front and back surfaces, providing excellent protection against UV light in the 250-425nm range.
The lens is spherical in shape, with a base shape of a circle, and has a geometry that includes an inner radius of 0 and an outer radius of 0. The lens's thickness at the edge is 1.97mm, while the center thickness is 4.1mm. The effective focal length (EFL) is 6mm, and the radii of curvature for the first and second surfaces are 4.76mm and -4.76mm, respectively. The back focal length (BFL) is 4.38mm.
The lens is made of fused silica, a material with the material ID of mal-1965, which is known for its excellent transparency in the UV region. The wavelength for this lens is 587.6nm.
