48-775 25.0mm Dia. x 125.0mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm
The 48-775 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 125.0mm, 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. This material ensures high transmission in the visible and near-infrared regions, making the lens suitable for use in a wide range of wavelengths, specifically from 600-1050nm.
The 48-775 features a front and back coating of EDM NIR-I STD Curve. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission and improving overall system efficiency. The coating is designed to perform optimally in the near-infrared region, aligning with the lens's material properties.
The lens's geometry includes a thickness edge of 2.28mm and a thickness center of 3.5mm. The inner and outer radii are 0mm, indicating a plano surface on one side and a curved surface on the other. The lens's effective focal length (EFL) is 122.7mm, and its radius of curvature (R1) is 64.62mm.
