LA1401-C N-BK7 Plano-Convex Lens; Dia:2 in; f=60.0 mm ARC 1050-1700nm
The LA1401-C is a plano-convex lens made from 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 2 inches (50.8 mm) and a focal length of 60.0 mm. The lens's design, with a spherical shape and a plano-convex base, allows for efficient light collection and focusing.
The lens's geometry includes a thickness of 3 mm at the edge and 16.3 mm at the center, providing a solid structure for various applications. The effective focal length (EFL) is 60 mm, which, combined with the lens's diameter, allows for a wide field of view. The radius of curvature (R1) is 30.9 mm, and the back focal length (BFL) is 49.1 mm, contributing to the lens's overall optical performance.
The LA1401-C is coated with a broadband anti-reflection coating (ARC) suitable for wavelengths between 1050 nm and 1700 nm. This coating reduces surface reflections, enhancing the lens's transmission and overall performance in the specified wavelength range.
