LA1727-AB 50.8 mm Dia. N-BK7 Plano-Convex Lens; EFL=750mm 400-1100nm
The LA1727-AB is a Plano-Convex Lens with a diameter of 50.8 mm, sourced from the reputable vendor Thorlabs. This lens is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties and versatility. The lens has a focal length (EFL) of 750mm, making it suitable for applications that require long focal lengths.
The lens's geometry includes a 3mm thickness at the edge and a 3.8mm thickness at the center. The front surface has a radius of curvature of 386.3mm, while the back surface is planar. The lens does not have any inner or outer radius specified, indicating a uniform curvature.
The LA1727-AB is coated with THo AB BAR on both the front and back surfaces. This anti-reflection coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission. The coating is designed to operate within the wavelength range of 400-1100nm, making it suitable for a broad spectrum of applications.
