88-708-INK 18.0mm Dia. x 72.0mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm

The 88-708-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 18.0mm, is designed for use in the visible light spectrum, specifically between 350-700nm, making it suitable for a wide range of optical applications.

The lens features a front and back coating of EDM VIS EXT, which is a broadband anti-reflection coating designed for use in the visible spectrum. This coating helps to reduce surface reflections, thereby increasing the amount of light transmitted through the lens.

The lens has a thickness of 1.9mm at the edge and 3.0mm at the center, with a focal length (EFL) of 72.0mm. The inner radius is 0mm, and the outer radius is also 0mm, indicating a plano surface on one side and a curved surface on the other. The radius of curvature (R1) of the curved surface is 37.22mm, and the back focal length (BFL) is 70.05mm.

The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and relatively low cost. This material is known for its low dispersion and high Abbe number, making it an ideal choice for many optical systems.
