63-552 20mm Dia. x 50mm FL; Uncoated; Double-Convex Lens

The 63-552 is a 20mm diameter, 50mm focal length double-convex lens offered by Edmund Optics. This lens is uncoated and features a base shape of a circle, with a standard spherical geometry. The lens's geometry includes a thickness of 1.52mm at the edge and 3.5mm at the center, with an effective focal length (EFL) of 50mm and a back focal length (BFL) of 48.84mm.

The lens is made of n-BK7 Schott material, a popular choice for its high refractive index and low dispersion. The radii of curvature for this lens are r1: 51.08mm and r2: -51.08mm. The lens is designed to operate at a wavelength of 587.6nm.

This lens is a convex-convex (double-convex) type, meaning it has two spherical surfaces that curve outwards. This design is often used to increase the convergence of light rays, making it ideal for use in applications such as microscopy, beam shaping, and laser focusing.

Please note that the lens is uncoated, which means it does not have any anti-reflective or protective coatings. This may result in a higher level of reflection at the lens surfaces, which could affect the overall performance of the lens in certain applications. However, uncoated lenses are often preferred in applications where cost, simplicity, or specific optical characteristics are a priority.
