The 38-468 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts an 18.0mm diameter and a 20.0mm focal length (FL), making it suitable for a wide range of optical applications. The lens is made from n-sf11 Schott, a high-index glass with excellent optical properties.
The lens features a plano-convex geometry, meaning one side is flat (plano), and the other side is curved (convex). The radius of curvature for the curved side is 15.7mm, and the back focal length (BFL) is 17.59mm. The lens has a central thickness of 4.3mm and an edge thickness of 1.46mm, providing robustness and durability.
The 38-468 lens is coated with EDM VIS EXT on both the front and back surfaces. This coating enhances the lens's performance in the visible spectrum, specifically between 350-700nm. It improves the lens's transmission, reduces reflection, and increases overall optical efficiency.
