40mm Diameter x 60mm FL Double-Convex Lens with Visible Light Coating from Edmund Optics
This item is a 40mm diameter x 60mm focal length double-convex lens, designed for use with visible light. The lens is sourced from the reputable optical components vendor, Edmund Optics, and is currently in stock with valid weblinks provided for easy reference.
The lens is spherical in shape, with a base shape of a circle. It features a double-convex geometry, characterized by its diameter of 40mm, thickness at the edge of 2mm, and thickness at the center of 8.8mm. The effective focal length (EFL) is 60mm, and the back focal length (BFL) is 57.1mm. The radii of curvature for the first and second surfaces are 60.56mm and -60.56mm, respectively.
The lens is made from the material N-BK7 Schott, a popular choice for optical elements due to its excellent optical properties and wide transparency range. The lens is coated with the EDM VIS-0 STD CURVE coating on both the front and back surfaces, designed to enhance its performance in the visible light spectrum, specifically at a wavelength of 587.6nm.
