88-761-INK 50.0mm Dia. x 75.0mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm
The 88-761-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 50.0mm, is designed to be used in the visible light spectrum, specifically between 350-700nm, making it suitable for a wide range of optical applications.
The lens features a geometry that includes a thickness of 1.86mm at the edge and 11mm at the center. The effective focal length (EFL) is 75.0mm, and the radius of curvature (R1) is 38.76mm. The back focal length (BFL) is 67.75mm, and both the inner and outer radii are 0mm, indicating a plano surface on the opposite side of the convex surface.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The lens is coated with EDM VIS EXT on both the front and back surfaces, enhancing its performance in the visible light spectrum.
