88-693-INK 15.0mm Dia. x 15.0mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm
The 88-693-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 visible light spectrum, specifically between 350-700nm. The lens features a front and back coating of EDM VIS EXT, which is a broadband anti-reflection coating designed for visible light.
The lens has a thickness of 2.16mm at the edge and 5.5mm at the center. The effective focal length (EFL) of the lens is 15mm, and the radius of curvature (R1) is 10.09mm. The back focal length (BFL) of the lens is 11.71mm. The lens is made of N-SF5 Schott, a high-index glass with excellent transparency in the visible spectrum.
The lens is inked, which is a process where a dye is applied to the edge of the lens to indicate its orientation. This is particularly useful in applications where the lens may be installed in a system where the orientation is not immediately apparent.
