88-690-INK 12.7mm Dia. x 38.1mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm
The 88-690-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.7mm, is designed for use within the visible light spectrum, specifically optimized for 587.6nm. The lens features a front and back coating of EDM VIS EXT, which enhances its performance within the specified wavelength range.
The lens has a base shape of a circle and a thickness at the edge of 1.95mm, while the center thickness is 3mm. The effective focal length (EFL) of this lens is 38.1mm, and the radius of curvature (R1) is 19.69mm. The back focal length (BFL) is 36.12mm, and both the inner and outer radii are 0mm.
This lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens is inked, which is a process that adds a dye to the lens to enhance contrast and make it easier to handle during assembly.
The 88-690-INK lens is currently in stock and available for immediate purchase. For more detailed information, please refer to the vendor's website.
