67-560-INK 25.4mm Dia. x 25.4mm FL; NIR II; Inked; Plano-Convex Lens NIR II 750-1550nm
The 67-560-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 25.4mm, is designed for use in the Near-Infrared II (NIR II) spectrum, specifically for wavelengths between 750nm and 1550nm.
The lens features a front and back coating of edm nir-ii std curve, which is specifically designed for use in the NIR II spectrum. This coating enhances the lens' performance in this region, providing superior transmission and reducing unwanted reflections.
The lens has a thickness of 2.82mm at the edge and 3.2mm at the center. The effective focal length (EFL) of the lens is 400mm, making it suitable for use in a variety of optical systems. The lens's inner radius is 0mm, and the outer radius is also 0mm, indicating a uniform curvature.
The lens's base shape is circular, and its geometry is plano-convex, meaning one side is flat (plano) and the other side is curved (convex). The radius of curvature (R1) of the curved side is 206.72mm. The back focal length (BFL) of the lens is 397.89mm.
This lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. The lens is inked, which is a process that adds a dye to the lens to make it easier to handle and identify.
