The LA4380-C UVFS Plano-Convex Lens is a high-quality optical component sourced from Thorlabs, a leading vendor in the field of optical equipment. This lens, with a diameter of 1 inch and a focal length of 100 mm, is designed for use in the ultraviolet to near-infrared spectrum, specifically between 1050nm and 1700nm.
The lens is spherical in shape, with a base shape of a circle. It features a plano-convex geometry, where one side is flat, and the other side is curved. The flat side, or the 'plano' side, has a thickness of 2mm, while the curved side, or the 'convex' side, has a thickness of 3.8mm at the center. The lens's effective focal length (EFL) is 100.3mm, and the radius of curvature (R1) is 46mm. The back focal length (BFL) is 97.7mm, and the lens has no inner or outer radius.
The LA4380-C UVFS Plano-Convex Lens is made from UVFS material with the Mal-1965 material ID. It is coated with a broadband anti-reflection coating (BBAR) on both the front and back surfaces, which enhances its performance in the specified wavelength range by reducing surface reflections.
