63-533 5mm Dia. x 20mm FL; Uncoated; Double-Convex Lens
The 63-533 is a 5mm diameter, double-convex lens with a 20mm focal length, sourced from the reputable optical components vendor, Edmund Optics. This lens, with its spherical geometry, is designed for use in a wide range of optical applications, thanks to its uncoated surface, which allows for versatile compatibility with various wavelengths.
The lens's base shape is circular, and it features an inner radius of 0mm and an outer radius of 0mm. The edge thickness measures 1.19mm, while the center thickness is slightly greater at 1.5mm. The effective focal length (EFL) is 20mm, and the back focal length (BFL) is 19.5mm. The radii of curvature for the first and second surfaces are R1: 20.41mm and R2: -20.41mm, respectively.
The lens is crafted from the high-quality material, n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties. The wavelength for this particular lens is 587.6nm. The lens's coating is currently listed as 'uncoated,' which means it does not have any additional anti-reflective or protective coatings.
