88-704-INK 18.0mm Dia. x 22.5mm FL; VIS-EXT; Inked; Plano-Convex Lens VIS-EXT 350-700nm
The 88-704-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, as indicated by its VIS-EXT coating on both the front and back surfaces.
The lens has a base shape of a circle and a thickness of 1.53mm at the edge, increasing to 4mm at the center. The effective focal length (EFL) of this lens is 22.5mm, and the radius of curvature (R1) is 17.66mm. The back focal length (BFL) is 20.26mm. The lens is made from n-sf11 Schott material, a high-index glass known for its excellent optical properties.
The lens's coating, VIS-EXT, is a broadband anti-reflection coating designed for high transmission in the visible spectrum. This coating reduces surface reflections and increases the amount of light transmitted through the lens, enhancing the overall performance of the optical system in which it is used.
Please note that the lens's inner and outer radii are both 0, indicating that this lens is a simple Plano-Convex lens with no additional curvature or features on the uncoated side. This lens is a versatile and high-performing option for applications that require a lens in the visible light spectrum.
