This is a plano-convex lens, type of spherical lens, sourced from the renowned optical components vendor, Edmund Optics. The lens, identified with the product code 63-524-INK, has a circular base shape and is designed for use within the visible to near-infrared (VIS-NIR) spectrum, specifically catering to wavelengths of 587.6nm.
The lens exhibits a diameter of 10.0mm and a thickness at the edge of 2.39mm, while the center thickness measures 3.0mm. The effective focal length (EFL) is 40.0mm, and the radius of curvature (R1) is 20.67mm. The back focal length (BFL) is 38.02mm, and the lens does not have any inner or outer radius specified.
The lens is made of N-BK7 Schott, a popular optical glass, and is coated with a VIS-NIR coating (edm visnir0sp2002000) on both the front and back surfaces. This coating enhances the lens's performance within the VIS-NIR spectrum, providing improved transmission and reduced reflection.
