48-762-INK 20.0mm Dia. x 70.0mm FL; NIR I; Inked; Plano-Convex Lens NIR I 600-1050nm
The 48-762-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 20.0mm, is designed for use in the near-infrared (NIR) spectrum, specifically between 600-1050nm. The lens features a front and back coating of edm nir-i std curve, providing optimal performance within its designated spectrum.
The lens has a thickness of 1.59mm at the edge and 3.0mm at the center, with an effective focal length (EFL) of 70.0mm. The radius of curvature for the first surface (R1) is 36.18mm, and the back focal length (BFL) is 68.03mm. The lens is made from n-bk7 schott, a popular material for optical elements due to its excellent optical properties.
The lens's geometry is circular, and it does not have any inner or outer radius specified, indicating a uniform curvature. The lens is inked, a process that aids in identifying and handling the lens during assembly and use.
