48-315 25.0mm Dia. x -50 FL; Uncoated; UV Plano-Concave Lens
The 48-315 is a 25.0mm diameter Plano-Concave lens with a focal length of -50 from Edmund Optics. This lens is uncoated and optimized for use in the ultraviolet (UV) spectrum, specifically at a wavelength of 587.6nm.
The lens's geometry includes an edge thickness of 5.52mm and a center thickness of 2mm. The inner and outer radii are both zero, indicating a planar surface on one side and a concave surface on the other. The radius of curvature (R1) of the concave surface is -22.92mm, and the back focal length (BFL) is -51.37mm.
This lens is made of fused silica (mal-1965), a material known for its excellent transparency in the UV region. The uncoated version of this lens is ideal for applications where cost-effectiveness is a priority and where the user can manage the reflected light.
