LA1258-AB 25.4 mm Dia. N-BK7 Plano-Convex Lens; EFL=2000mm 400-1100nm

The LA1258-AB is a 25.4 mm diameter Plano-Convex lens made from N-BK7 Schott glass, featuring an effective focal length (EFL) of 2000mm and designed for use within the wavelength range of 400-1100nm. This lens is sourced from Thorlabs, a reputable vendor known for their high-quality optical components.

The Plano-Convex design of this lens consists of a flat (plano) surface and a curved (convex) surface. The curvature of the convex surface is defined by a radius of 1033.6mm. The lens has a thickness of 2mm at the edge and 2.1mm at the center. This specific lens is part of Thorlabs' extensive catalog of Spherical Lenses, which are characterized by their curvature being described by a single spherical radius.

The LA1258-AB lens is coated with Thorlabs' AR coating (tho ab bbar) on both the front and back surfaces to minimize reflection losses and ensure optimal performance. This lens is available for purchase directly from the Thorlabs website, where you can find the most up-to-date information regarding its availability and pricing.
