LA1213-A N-BK7 Plano-Convex Lens; Dia:0.5 in; f=50.0 mm ARC 350-700nm
The LA1213-A is a high-quality plano-convex lens from Thorlabs, designed for use in a wide range of optical applications. This lens is made from N-BK7 glass, a popular material for its excellent optical properties and high transmission in the visible spectrum.
The lens has a diameter of 0.5 inches (12.7 mm) and a focal length of 50.0 mm, making it suitable for use in systems where a long focal length is required. The lens is 1.8 mm thick at the edge and 2.6 mm thick at the center, providing a robust structure while maintaining a low profile.
The LA1213-A features an anti-reflection coating, specifically designed for the ARC 350-700nm range. This coating reduces surface reflections, improving the overall transmission of the lens and enhancing the performance of your optical system.
The lens's geometry is spherical, with a radius of curvature of 25.8 mm on the convex side. This shape, combined with the lens's high-quality glass and precise manufacturing, ensures excellent image quality and low distortion.
