48-773 25.0mm Dia. x 85.0mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm
The 48-773 is a Plano-Convex Spherical Lens, sourced from the renowned optical components vendor, Edmund Optics. This lens boasts a diameter of 25.0mm and a focal length of 85.0mm, making it a versatile choice for various optical applications.
The lens is crafted from the high-quality material, N-BK7 Schott, a borosilicate glass known for its excellent optical properties, including high transparency and low autofluorescence. This material is particularly suitable for use in the near-infrared (NIR) spectrum, specifically between 600-1050nm, as indicated by the lens's coating.
The 48-773 features a front and back coating of EDM NIR-I STD Curve, a specialized coating designed to enhance performance in the NIR spectrum. This coating aids in reducing surface reflections, thereby improving transmission and overall system efficiency.
The lens's geometry is another notable feature. It has an edge thickness of 2.48mm and a center thickness of 4.3mm, with an effective focal length (EFL) of 85mm. The inner and outer radii are 0mm, and the lens's base shape is circular. The radius of curvature (R1) is 43.93mm, and the back focal length (BFL) is 82.17mm.
