38-472-INK 25.4mm Dia. x 35.0mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm
The 38-472-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 1.69mm. The center thickness is 6.9mm, and the effective focal length (EFL) is 35mm. The lens's front radius of curvature (R1) is 18.09mm, and the back focal length (BFL) is 30.46mm.
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 surfaces, a coating designed for use in the visible spectrum, specifically between 350-700nm. This coating enhances the lens's transmission and reduces reflection, making it ideal for applications that require high light transmission.
The lens's geometry, including its inner and outer radii, is not specified, indicating that these dimensions are either not applicable or not provided. The wavelength of the lens is 587.6nm, a standard reference wavelength in the middle of the visible spectrum.
