38-419-INK 18.0mm Dia. x 30.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 38-419-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 18.0mm, is designed for use in the near-infrared (NIR) spectrum, specifically between 750nm and 1550nm, as indicated by its NIR II coating.
The lens features a front and back coating of edm nir-ii std curve, which is standard for this type of lens. The lens's geometry includes a thickness edge of 1.52mm and a thickness center of 4.4mm. The effective focal length (EFL) is 30.0mm, and the radius of curvature (R1) is 15.51mm. The back focal length (BFL) is 27.1mm, and both the inner and outer radii are 0mm.
The lens is made of n-bk7 schott, a common material for optical lenses due to its excellent optical properties. The lens is inked, which is a process that adds a dye or pigment to the lens to enhance its visibility or to mark it for identification purposes.
This lens is currently in stock and available for purchase through the Edmund Optics website. Its detailed specifications make it a suitable choice for users looking for a NIR II Plano-Convex lens with specific geometric and material properties.
