LA1608-D N-BK7 Plano-Convex Lens; Dia:1 in; f=75.0 mm ARC 1650-3000nm
The LA1608-D 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 1 inch (25.4 mm) and a focal length of 75.0 mm. The lens's geometry includes a thickness of 2 mm at the edge and 4.1 mm at the center, with an effective focal length (EFL) of 74.7 mm.
The lens's front and back surfaces are coated with ARC 1650-3000nm, a broadband anti-reflection coating designed to reduce surface reflections and increase transmission in the 1650-3000nm wavelength range. This coating enhances the lens's performance in infrared applications.
The LA1608-D's shape is spherical, with a radius of curvature (R1) of 38.6 mm on the curved surface. The back surface is planar, and the lens has no inner or outer radius. The lens's material ID is n-bk7 schott, indicating its composition and origin.
