48-741 12.0mm Dia. x 60.0mm FL; NIR I Coated; Plano-Convex Lens NIR I 600-1050nm
The 48-741 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a 12.0mm diameter and a focal length of 60.0mm, making it suitable for a wide range of 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 near-infrared coating designed to enhance the lens' performance in the 600-1050nm wavelength range. This coating helps to reduce surface reflections, improving the lens' overall efficiency and light transmission.
The geometry of the lens includes a thickness edge of 1.91mm and a thickness center of 2.5mm. The lens' inner radius is 0mm, and the outer radius is also 0mm, indicating a uniform curvature. The lens' effective focal length (EFL) is 60mm, and the back focal length (BFL) is 58.37mm.
The lens's curvature is defined by a radius of 31.02mm on the curved side. This curvature, combined with the lens's material and coating, contributes to its excellent optical performance.
