LA1027-AB 25.4 mm Dia. N-BK7 Plano-Convex Lens; EFL=35mm 400-1100nm
The LA1027-AB is a 25.4 mm diameter Plano-Convex lens made from N-BK7 Schott glass, sourced from the reputable vendor Thorlabs. This lens is designed for use within a broad wavelength range of 400-1100nm, making it a versatile choice for various optical applications.
The lens geometry features a convex surface with a radius of curvature of 18mm, while the planar surface is flat. The lens has a center thickness of 7.2mm and an edge thickness of 2mm, providing a robust structure suitable for precise optical work. The effective focal length (EFL) of this lens is 34.9mm, which is a crucial parameter for determining the lens's focusing capabilities.
The LA1027-AB lens comes with anti-reflection broadband coatings on both the front and back surfaces, denoted as 'tho ab bbar'. These coatings are designed to minimize surface reflections and increase transmission within the specified wavelength range, thereby enhancing the overall performance of the lens.
