The 38-313-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 18.0mm and a focal length of 20.0mm, is designed for use in the visible light spectrum, specifically at 587.6nm. The lens features a front and back coating of edm vis-0 std curve, providing standard curve performance for the visible light range.
The lens geometry includes an inner radius of 0mm and an outer radius of 0mm, with a thickness at the edge of 1.46mm and a thickness at the center of 4.3mm. The back focal length (BFL) is 17.59mm, and the effective focal length (EFL) is 20mm. The lens is made from n-sf11 Schott material, a high index glass with excellent transmittance in the visible and near-infrared regions.
