88-681 12.0mm Dia. x 60.0mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm
The 88-681 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 12.0mm, making it suitable for a wide range of optical applications. The lens has a thickness of 1.91mm at the edge and 2.5mm at the center, providing a robust structure.
The effective focal length (EFL) of this lens is 60.0mm, 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 31.02mm, and the back focal length (BFL) is 58.37mm. The lens does not have an inner radius or an outer radius.
The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. The lens is coated with EDM VIS EXT on both the front and back surfaces, enhancing its transmission capabilities within the visible spectrum (350-700nm).
