LA1258-B N-BK7 Plano-Convex Lens; Dia:1 in; f=2000.0 mm ARC 650-1050nm
The LA1258-B is a plano-convex lens with a diameter of 1 inch, designed for use in the 650-1050nm wavelength range. This lens is sourced from Thorlabs, a reputable vendor known for their high-quality optical components.
The lens is made from N-BK7, a popular glass type in the optical industry due to its excellent optical properties. The plano-convex geometry, where one side is flat and the other is curved, is ideal for a variety of applications. The lens has a focal length of 2000mm, indicated by the 'f=2000.0 mm' parameter.
The lens features anti-reflection coatings on both the front and back surfaces, specifically the 'tho b bbar' coating. These coatings are designed to reduce surface reflections, thereby increasing the amount of light transmitted through the lens.
The geometry of the lens includes a 2mm edge thickness and a 2.1mm center thickness. The inner and outer radii are both 0, indicating a flat inner surface and a curved outer surface. The radius of curvature (r1) is 1033.6mm, and the back focal length (bfl) is 1998.6mm.
