38-474-INK 25.4mm Dia. x 75.0mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm
The 38-474-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 25.4mm and a thickness at the edge of 1.36mm, while the center thickness measures 3.5mm. The effective focal length (EFL) of this lens is 75mm.
The lens's front and back surfaces are coated with EDM VIS EXT, a coating specifically designed for the visible spectrum, enhancing its performance in this range (350-700nm). The radius of curvature for the first surface (R1) is 38.76mm, and the back focal length (BFL) is 72.69mm.
The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens's geometry, including its inner and outer radii, is not specified, indicating that these dimensions are either not applicable or not provided.
