45-483-INK 12.0mm Dia. x 24.0mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm
The 45-483-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.0mm, is designed for use in the visible to near-infrared (VIS-NIR) spectrum, specifically catering to wavelengths between 400 and 1000nm.
The lens features a front and back coating of edm visnir0sp2002000, a proprietary coating by Edmund Optics that enhances its performance in the VIS-NIR spectrum. The lens has a thickness of 1.25mm at the edge, increasing to 2.8mm at the center, and an effective focal length (EFL) of 24mm.
The lens's inner radius is 0mm, and the outer radius is also 0mm, indicating a plano surface on the non-curved side. The radius of curvature (R1) of the curved surface is 12.42mm, and the back focal length (BFL) is 22.15mm.
This lens is made of n-bk7 schott, a high-quality optical glass known for its excellent transmittance and low auto-fluorescence. The lens is inked, a process that adds a layer of ink to the edge of the lens to prevent contamination and damage during handling and assembly.
