49-897-INK 12.0mm Dia. x 20.0mm FL; VIS 0deg; Inked; Plano-Convex Lens VIS 0° 425-675nm
This is a Plano-Convex lens, type 49-897-INK, sourced from Edmund Optics. The lens has a base shape of a circle and is designed for use in the visible light spectrum, specifically between 425-675nm. The lens features a Vis-0 coating on both the front and back surfaces, which is a standard curve coating provided by Edmund Optics.
The lens has a diameter of 12.0mm and a thickness at the edge of 1.58mm. The center thickness of the lens is 3.5mm, and it has an effective focal length (EFL) of 20.0mm. The radius of curvature for the first surface (R1) is 10.34mm, and the back focal length (BFL) is 17.69mm. The lens does not have an inner or outer radius.
The lens is made of N-BK7 Schott glass, a common material for optical lenses due to its excellent optical properties and wide transparency range. The lens is inked, which is a process where a dye is applied to the edge of the lens to indicate its orientation.
