The LA1074-AB is a 12.7 mm diameter Plano-Convex lens made from N-BK7 Schott glass, featuring an effective focal length (EFL) of 19.9 mm and designed for use within the wavelength range of 400-1100 nm. This lens is sourced from Thorlabs, a reputable vendor known for their high-quality optical components.
The lens's geometry includes a 1.8 mm thickness at the edge and a 4 mm thickness at the center, with a clear aperture allowing for optimal light transmission. The front and back surfaces are coated with a broadband anti-reflection (BBAR) coating, specifically THo AB Bbar, which enhances the lens's performance by minimizing surface reflections and improving overall transmission.
The Plano-Convex design of this lens, combined with its spherical shape, ensures excellent imaging quality and low spherical aberration. The 10.3 mm radius of curvature on the convex side further contributes to the lens's high-performance capabilities.
For users seeking a reliable and high-performing lens within the specified wavelength range, the LA1074-AB is an excellent choice. Its combination of N-BK7 Schott glass, Plano-Convex design, and BBAR coating ensures optimal light transmission, minimal surface reflections, and reduced spherical aberration, making it suitable for a wide range of applications.
