LA1131-A N-BK7 Plano-Convex Lens; Dia:1 in; f=50.0 mm ARC 350-700nm
The LA1131-A 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 lens's geometry includes a thickness of 2 mm at the edge and 5.3 mm at the center, with an effective focal length (EFL) of 50 mm.
The lens's front and back surfaces are coated with ARC 350-700nm coating, designed to reduce reflection and increase transmission in the 350-700nm wavelength range. This coating enhances the lens's performance in various applications, including imaging, beam shaping, and laser systems.
The lens's base shape is circular, and its geometry is spherical, which is common in optical systems due to its ease of manufacturing and good imaging quality. The lens's inner and outer radii are 0, indicating a plano surface on one side and a curved surface on the other.
