67-519-INK 15.0mm Dia. x 30.0mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-519-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 15.0mm, is designed for use in the Near-Infrared II (NIR II) spectrum, specifically between 750-1550nm. The lens features a front and back coating of edm nir-ii std curve, which enhances its performance in the NIR II range.
The lens has a thickness of 1.52mm at the edge and 3.8mm at the center, providing a base shape that is circular. The effective focal length (EFL) of this lens is 20mm, and the radius of curvature (R1) is 13.46mm. The back focal length (BFL) is 17.74mm, and the lens does not have an inner or outer radius.
The material ID for this lens is n-sf5 schott, a common material used in optical applications due to its excellent transmission properties in the NIR II range. The lens is inked, which is a process that adds a dye or pigment to the lens to make it more visible and easier to handle.
This lens is currently in stock and available for purchase on the Edmund Optics website. Its detailed specifications make it an ideal choice for users looking for a high-performance lens in the NIR II range.
