88-726-INK 25.0mm Dia. x 75.0mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm
The 88-726-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a base shape of a circle, has a diameter of 25.0mm and a thickness at the edge of 2.43mm, while the center thickness is 4.5mm. The effective focal length (EFL) of this lens is 75.0mm, and the radius of curvature (R1) is 38.76mm. The back focal length (BFL) is 72.0mm, and the lens does not have an inner or outer radius.
The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens is coated with EDM VIS EXT on both the front and back, a coating that extends the visible range of the lens to 350-700nm. This coating enhances the lens's performance in transmitting and reflecting light, making it suitable for various applications.
