38-334 9.0mm Dia. x 25mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm
The 38-334 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a 9.0mm diameter and a focal length of 25mm, making it suitable for a wide range of optical applications. The lens is made from N-BK7 Schott, a popular optical glass known for its excellent transparency and low dispersion.
The lens features a front and back coating of EDM NIR-I STD Curve, a specialized coating designed for use in the near-infrared spectrum, specifically between 600-1050nm. This coating enhances the lens's performance in the NIR range, improving its transmission and reducing unwanted reflections.
The geometry of the lens includes a thickness of 1.19mm at the edge and 2mm at the center. The inner and outer radii are 0, indicating a plano surface on one side and a curved surface on the other. The lens's effective focal length (EFL) is 25mm, and the back focal length (BFL) is 23.68mm.
