63-553 20mm Dia. x 60mm FL; Uncoated; Double-Convex Lens
The 63-553 is a 20mm diameter, double-convex lens with a 60mm focal length, sourced from the renowned optical components vendor, Edmund Optics. This lens, with its uncoated surface, is designed for applications where coating is not a necessity or may even be detrimental.
The lens's base shape is circular, and it features a double-convex geometry, meaning both surfaces are curved outwards. The diameter of the lens is 20mm, and the edge thickness measures 2.36mm. The center thickness is 4mm, providing a solid structure for the lens.
The effective focal length (EFL) of the lens is 60mm, which is the distance from the lens's center to the point where light rays converge. The first radius of curvature (R1) is 61.33mm, and the second radius (R2) is -61.33mm, indicating the lens's double-convex nature. The back focal length (BFL) is 58.67mm, which is the distance from the lens's rear surface to the point where the light rays converge.
The lens is made of n-BK7 Schott, a popular optical glass known for its excellent optical properties. The wavelength for this lens is 587.6nm, which is in the visible light spectrum. The lens's shape is spherical, and it has no coating, making it suitable for applications where coating might introduce unwanted reflections or interfere with the optical path.
