38-332 9.0mm Dia. x 10mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm
The 38-332 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a 9.0mm diameter and a 10mm focal length (FL), making it suitable for a wide range of applications. The lens is fabricated from n-SF11 Schott, a high-index glass with excellent transmittance 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 curvature of the convex side is defined by a radius of 7.85mm. This geometry results in a back focal length (BFL) of 8.49mm and an effective focal length (EFL) of 10mm. The lens's edge thickness is 1.28mm, while the center thickness is 2.7mm, providing structural integrity and resistance to deformation.
The 38-332 lens is coated with Edmund Optics' NIR I standard curve on both the front and back surfaces. This coating enhances the lens's performance in the NIR region, specifically between 600nm and 1050nm, by reducing surface reflections and increasing transmission.
