48-726 9.0mm Dia. x 13.5mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm
This 48-726 Plano-Convex Lens, sourced from Edmund Optics, is a spherical lens with a 9.0mm diameter and a 13.5mm focal length. The lens is made from n-SF5 Schott, a high-quality optical material known for its excellent transmission properties in the near-infrared (NIR) region.
The lens features a plano-convex geometry, meaning one side is flat (plano) and the other side is curved (convex). The radius of curvature of the convex side is 9.09mm, and the lens has a central thickness of 2.6mm and an edge thickness of 1.41mm. The back focal length (BFL) is 11.94mm, and the effective focal length (EFL) is 13.5mm.
The lens is coated with Edmund Optics' NIR I standard curve coating on both the front and back surfaces. This coating is designed to enhance the lens' performance in the NIR region, specifically between 600nm and 1050nm. The coating reduces surface reflections, improving transmission and increasing the lens' overall efficiency.
