88-704 18.0mm Dia. x 22.5mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm
The 88-704 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 18.0mm, making it suitable for a wide range of optical applications. The lens has a thickness of 1.53mm at the edge and 4.0mm at the center, providing a balanced structure for efficient light transmission.
The effective focal length (EFL) of this lens is 22.5mm, which is the distance from the lens's center to the focal point where light rays converge. The first radius of curvature (R1) is 17.66mm, and the back focal length (BFL) is 20.26mm. The lens does not have an inner or outer radius.
The lens is made of n-SF11 Schott, a high-index glass with excellent optical properties. It is designed to work with a wavelength of 587.6nm, which is in the visible light spectrum. The lens is coated with EDM VIS-EXT on both the front and back, enhancing its transmission capabilities within the visible light spectrum (350-700nm).
