88-713-INK 20.0mm Dia. x 40.0mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm
The 88-713-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 20.0mm, is designed for use within the visible light spectrum, specifically optimized for wavelengths of 587.6nm.
The lens features a front and back coating of EDM VIS EXT, a coating type known for its broadband anti-reflection properties, which enhances transmission and reduces surface reflections. The lens has a thickness of 2.32mm at the edge and 4.9mm at the center, with a focal length (EFL) of 40.0mm.
The lens's front surface has a radius of curvature (R1) of 20.67mm, and the back focal length (BFL) is 36.77mm. The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number.
The lens's geometry is circular, and it is inked, indicating that it has been marked for identification or alignment purposes. This lens is a great choice for applications that require a broadband anti-reflection coated, plano-convex lens within the visible light spectrum.
