48-252-INK 50.0mm Dia. x 500.0mm FL; VIS 0deg; Inked; Plano-Convex Lens VIS 0° 425-675nm
The 48-252-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 50.0mm, is designed for use within the visible light spectrum, specifically between 425-675nm. The lens features a front and back coating of edm vis-0 std curve, providing a standard curve for optimal performance within its designated wavelength range.
The lens has a base shape of a circle and a thickness at the edge of 3.79mm, while the center thickness measures 5.0mm. The effective focal length (EFL) of this lens is 500.0mm, and the radius of curvature (R1) is 258.4mm. The back focal length (BFL) is 496.7mm, and the lens does not have an inner or outer radius.
The material of this lens is n-bk7 schott, a common material for optical lenses due to its high refractive index and low dispersion. This makes it ideal for applications that require high image quality and low chromatic aberration.
The lens is inked, a process that applies a dye or pigment to the surface of the lens. This can be used for marking or identification purposes, or it can be used to reduce surface reflections.
