LA1540-AB 12.7 mm Dia. N-BK7 Plano-Convex Lens; EFL=15mm 400-1100nm
The LA1540-AB is a 12.7 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 1100 nanometers, making it a versatile choice for various optical applications.
The lens features an effective focal length (EFL) of 15mm, which is a crucial factor in determining the lens's magnification power. The EFL, combined with the lens's diameter, allows for precise control over the light path, enabling the creation of focused, clear images.
The LA1540-AB has a convex shape on one side, with a radius of curvature of 7.7mm, and is plano on the other side. The thickness at the edge of the lens is 1.8mm, while the center thickness is 5.1mm. This specific geometry is designed to minimize spherical aberration, ensuring optimal image quality.
The lens is coated with THo AB Bbar on both the front and back surfaces. This anti-reflection coating reduces surface reflections, thereby increasing transmission and improving overall system performance.
