38-458-INK 12.5mm Dia. x 45.0mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm
The 38-458-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.5mm, is designed for use within the visible light spectrum, specifically between 350-700nm. The lens features a front and back coating of edm vis ext, which is a broadband anti-reflection coating designed for high transmission in the visible spectrum.
The lens has a thickness of 1.14mm at the edge and 2mm at the center, with a focal length (EFL) of 45mm. The front surface of the lens has a radius of curvature (R1) of 23.26mm, and the back focal length (BFL) is 43.68mm. The 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 where a dye is applied to the edge of the lens to indicate the orientation. This is particularly useful in applications where the lens may be installed in a system where the orientation is not immediately apparent.
