88-764-INK 50.0mm Dia. x 150.0mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm
The 88-764-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 50.0mm and a thickness at the edge of 4.86mm, while the center thickness is 9.0mm. The effective focal length (EFL) of this lens is 150.0mm, making it suitable for a variety of optical applications.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. The front and back of the lens are coated with EDm VIS-EXT, a coating designed for visible light with wavelengths between 350-700nm. This coating enhances the lens's transmission in the visible spectrum, making it ideal for applications where high transmittance is required.
The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm, indicating a plano surface on one side and a curved surface on the other. The curvature of the lens is defined by a radius of 77.52mm on the curved side. The back focal length (BFL) of the lens is 144.07mm.
