88-678-INK 12.0mm Dia. x 42.0mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm
The 88-678-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 12.0mm, 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 geometry of the lens includes a thickness of 1.85mm at the edge and 2.7mm at the center. The Effective Focal Length (EFL) is 42.0mm, and the Radius of Curvature (R1) is 21.71mm. The Back Focal Length (BFL) is 46.36mm, and both the Inner and Outer Radius are 0mm.
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 applications.
