88-717 20.0mm Dia. x 80.0mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm
The 88-717 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens has a base shape of a circle and a diameter of 20.0mm, making it suitable for a wide range of optical applications. The lens has a thickness of 1.13mm at the edge and 2.35mm at the center, providing a robust structure.
The effective focal length (EFL) of this lens is 80.0mm, which is the distance from the lens's center to the focal point when the lens is imaging an object at infinity. The first radius of curvature (R1) is 41.48mm, and the back focal length (BFL) is 78.45mm. The lens does not have an inner radius or an outer radius.
The lens is made of n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence. This material is suitable for use in the visible spectrum, specifically between 350-700nm, as indicated by the VIS-EXT coating on both the front and back surfaces. This coating enhances the lens's transmission in the visible spectrum, making it ideal for applications that require high light transmission.
