LA1134-B N-BK7 Plano-Convex Lens; Dia:1 in; f=60.0 m ARC 650-1050nm
The LA1134-B 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, is designed with a 1-inch diameter and a focal length of 60 meters, making it suitable for a wide range of applications.
The lens's geometry is characterized by a 25.4 mm diameter, a 2 mm thickness at the edge, and a 4.7 mm thickness at the center. The effective focal length (EFL) is 60 mm, and the radius of curvature (ROC) of the curved surface is 30.9 mm. The back focal length (BFL) is 56.7 mm, and both the inner and outer radii are 0 mm.
The LA1134-B is coated with a broadband anti-reflection coating, specifically the Thorlabs BBAR coating, designed for the 650-1050 nm wavelength range. This coating reduces surface reflections, enhancing the lens's performance in transmitting light.
This lens is a spherical lens, meaning it has a spherical surface. The spherical shape ensures a consistent curvature across the lens's surface, which is beneficial for imaging applications.
