88-743-INK 25.4mm Dia. x 88.9mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm
The 88-743-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 visible light spectrum, specifically between 350-700nm, as indicated by its VIS-EXT coating on both the front and back surfaces.
The lens has a base shape of a circle and a thickness of 2.21mm at the edge, while the center thickness is 4mm. The effective focal length (EFL) of this lens is 88.9mm, and the radius of curvature (R1) is 45.94mm. The back focal length (BFL) is 86.26mm, and the lens does not have an inner or outer radius.
The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens's coating, VIS-EXT, is designed to enhance its performance in the visible light spectrum.
