38-309-INK 12.7mm Dia. x 40.0mm FL; VIS 0deg; Inked; Plano-Convex Lens VIS 0° 425-675nm

The 38-309-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.7mm, is designed for use in the visible light spectrum, specifically between 425-675nm. The lens features a front and back coating of edm vis-0 std curve, which is a standard coating for this type of lens.

The lens has a base shape of circular and a thickness at the edge of 1.3mm, while the center thickness is 2.3mm. The effective focal length (EFL) of the lens is 40mm, and the radius of curvature (R1) is 20.67mm. The back focal length (BFL) of the lens is 38.48mm. The lens does not have an inner or outer radius.

The lens is made of n-bk7 schott, a common material for optical lenses due to its excellent optical properties. The lens is designed for a wavelength of 587.6nm, which is the wavelength of the green light in the visible spectrum.

The lens is inked, which is a process that adds a dye or pigment to the lens to make it more visible or to mark it for identification purposes. This lens is in stock and available for immediate purchase.
