LA1131-AB 25.4 mm Dia. N-BK7 Plano-Convex Lens; EFL=50mm 400-1100nm

The LA1131-AB is a 25.4 mm diameter Plano-Convex lens made from N-BK7 Schott glass, sourced from Thorlabs. This lens is designed for use within a broad wavelength range, from 400 to 1100nm, making it a versatile choice for various optical applications.

The lens geometry features a convex shape on one side with a 25.8mm radius of curvature. The lens has a central thickness of 5.3mm and an edge thickness of 2mm, providing a robust structure suitable for precise optical work. The effective focal length (EFL) of this lens is 49.8mm, which is a crucial parameter for determining the lens's focusing capabilities.

The LA1131-AB lens is coated with Thorlabs' Anti-Reflection (AR) coating, denoted as THo AR BBAR, on both the front and back surfaces. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission and improving overall system efficiency.
