LA1131-C N-BK7 Plano-Convex Lens; Dia:1 in; f=50.0 mm ARC 1050-1700nm
The LA1131-C is a plano-convex lens made of N-BK7 glass, a popular material in the optical industry due to its excellent optical properties. This lens, sourced from Thorlabs, has a diameter of 1 inch (25.4 mm) and a focal length of 50.0 mm. The plano-convex shape, where one side is flat and the other is curved, is designed to minimize spherical aberration, ensuring high-quality imaging.
The lens's geometry includes a thickness of 2 mm at the edge and 5.3 mm at the center. The effective focal length (EFL) is 50 mm, and the radius of curvature (R1) is 25.8 mm. The back focal length (BFL) is 46.3 mm, and both the inner and outer radii are 0 mm.
The LA1131-C is coated with a broadband anti-reflection coating (ARC) that covers the wavelength range of 1050-1700 nm. This coating reduces reflection and increases transmission, enhancing the lens's performance in various applications.
