25mm Dia. x 500mm FL Visible Light Coated UV Double-Convex Lens

This 25mm diameter x 500mm focal length visible light coated ultraviolet double-convex lens is a high-quality optical component sourced from Edmund Optics. The lens is designed with a spherical shape, featuring a standard visible (VIS) 0-degree coating on both the front and back surfaces.

The lens geometry includes a 3.01mm thickness at the edge and a 3.35mm thickness at the center, with an effective focal length (EFL) of 500mm. The first and second radii of curvature are 457.93mm and -457.93mm, respectively, resulting in a back focal length (BFL) of 498.85mm. The inner and outer radii are both 0mm, indicating a uniform curvature throughout the lens.

The lens is made from fused silica material, identified as mal-1965 in the material database. It is designed to operate within the visible light spectrum, with a central wavelength of 587.6nm. The standard visible coating on both surfaces helps to reduce surface reflections and improve transmission within the specified wavelength range.

This lens is a double-convex type, meaning it has two convex surfaces that converge light towards a focal point. This design is ideal for various applications, including imaging systems, beam shaping, and other optical engineering tasks.
