LA1509-C N-BK7 Plano-Convex Lens; Dia:1 in; f=100.0 mm ARC 1050-1700nm
The LA1509-C is a plano-convex lens, a type of spherical lens, featuring a base shape of a circle and sourced from the reputable vendor Thorlabs. This lens boasts a diameter of 1 inch (25.4 mm) and a center thickness of 3.6 mm, with an edge thickness of 2 mm. The effective focal length (EFL) of this lens is 100 mm, and the front radius of curvature (R1) is 51.5 mm. The back focal length (BFL) measures 97.3 mm, while the inner and outer radii are both 0 mm.
This lens is made of N-BK7, a popular glass type in the Schott catalog, which is known for its excellent optical properties. The wavelength for this lens is 587.6 nm. The lens features a coating on both the front and back surfaces, specifically the Thorlabs coating BBAR (Broadband Anti-Reflection), which is designed for the ARC range of 1050-1700 nm. This coating helps minimize surface reflections, thereby enhancing transmission and reducing optical losses.
