38-505-INK 12.5mm Dia. x 30.0mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm
The 38-505-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.5mm, is designed for use within the visible to near-infrared spectrum, specifically between 400-1000nm. The lens has a front (planar) side and a back (convex) side, both of which are coated with a VIS-NIR coating (edm visnir0sp2002000) to enhance its performance within this spectrum.
The lens has a thickness of 1.39mm at the edge and 2.7mm at the center, with an effective focal length (EFL) of 30mm. The radius of curvature for the first surface (R1) is 15.51mm, and the back focal length (BFL) is 28.22mm. 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 that adds a dye or paint to the edge of the lens. This can be useful for identifying the orientation of the lens or for distinguishing it from other lenses in a system. The lens is currently in stock and available for purchase through the Edmund Optics website.
