63-550 20mm Dia. x 20mm FL; Uncoated; Double-Convex Lens
The 63-550 20mm Dia. x 20mm FL; Uncoated; Double-Convex Lens is a high-quality optical component sourced from Edmund Optics. This lens, with its spherical geometry, is a Double-Convex type, featuring two convex surfaces that are designed to refract and focus light.
The lens has a diameter of 20mm and a base shape of a circle. The thickness at the edge of the lens is 1.6mm, while the center thickness is 5mm. The Effective Focal Length (EFL) is 20mm, indicating the distance from the lens's center to the point where it focuses light.
The lens is made from n-SF11 Schott, a high-index glass with excellent optical properties. The radii of curvature for the first and second surfaces are 30.25mm and -30.25mm, respectively. The Back Focal Length (BFL) is 18.55mm, which is the distance from the lens's rear surface to the point where it focuses light.
The lens does not have any coating, which means it is uncoated. This may result in reduced light transmission and increased reflection, but it also means the lens is more cost-effective and suitable for applications where such factors are not critical.
The wavelength for this lens is 587.6nm, which is in the visible light spectrum. This makes it suitable for applications that involve visible light, such as imaging systems, beam shaping, and light collimation.
