48-780 25.0mm Dia. x 500.0mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm
The 48-780 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 25.0mm and a focal length of 500.0mm, making it a versatile choice for various optical applications. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion.
The lens features a front and back coating of EDM NIR-I std curve, which is a broadband anti-reflection coating specifically designed for the near-infrared (NIR) spectrum, typically between 600-1050nm. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission and improving image quality.
The geometry of the lens includes a thickness edge of 2.9mm and a thickness center of 3.2mm. The inner and outer radii are 0mm, and the lens's effective focal length (EFL) is 500.89mm. The front surface has a radius of curvature of 258.4mm.
