LA1131-D N-BK7 Plano-Convex Lens; Dia:1 in; f=50.0 mm ARC 1650-3000nm
The LA1131-D is a plano-convex lens made from N-BK7 Schott glass, sourced from the reputable vendor Thorlabs. This lens boasts a diameter of 1 inch (25.4 mm) and a focal length of 50.0 mm, making it suitable for a wide range of optical applications.
The lens's geometry is characterized by a thickness of 2 mm at the edge and 5.3 mm at the center. The effective focal length (EFL) is 49.8 mm, and the radius of curvature (R1) is 25.8 mm. The back focal length (BFL) is 46.3 mm, and both the inner and outer radii are 0 mm.
The LA1131-D is coated with ARC, a coating that spans the wavelength range of 1650-3000nm on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, thereby improving the overall efficiency of the optical system.
