38-359 12.5mm Dia. x 35.0mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm
The 38-359 is a Plano-Convex Spherical Lens, sourced from Edmund Optics, designed for use within the near-infrared (NIR) spectrum of 600-1050nm. This lens boasts a circular base shape, with a 12.5mm diameter and a thickness of 1.29mm at the edge, increasing to 2.4mm at the center. The effective focal length (EFL) of this lens is 35mm, with a front radius (R1) of 18.09mm and a back focal length (BFL) of 33.42mm.
The lens is crafted from N-BK7 Schott glass, a material well-known for its excellent optical properties, including high homogeneity and low auto-fluorescence. This makes it an ideal choice for applications that require high precision and clarity.
The 38-359 lens features a standard NIR I coating on both the front and back surfaces. This coating is specifically designed to enhance performance within the NIR spectrum, ensuring optimal transmission and minimal reflection. The coating is part of Edmund Optics' standard curve, which guarantees consistent performance across all their NIR I coated products.
