LA1540-D N-BK7 Plano-Convex Lens; Dia:0.5 in; f=15.0 mm ARC 1650-3000nm
The LA1540-D is a plano-convex lens, a type of spherical lens, featuring a circular base shape and sourced from the reputable vendor, Thorlabs. This lens is designed for use within the wavelength range of 1650-3000nm, with a central wavelength of 587.6nm, and is constructed from the high-quality material, n-BK7 Schott.
The lens boasts a diameter of 12.7mm, with a thickness at the edge of 1.8mm and a center thickness of 5.1mm. The effective focal length (EFL) of this lens is 14.9mm, and the radius of curvature (R1) is 7.7mm. The back focal length (BFL) measures 11.6mm, while the inner and outer radii are both 0mm.
The LA1540-D is equipped with anti-reflection (AR) coating on both the front and back surfaces, specifically the "tho d bbar" coating. This coating enhances the lens's performance by minimizing surface reflections, thereby increasing transmission and reducing dispersion.
