LA1304-AB 12.7 mm Dia. N-BK7 Plano-Convex Lens; EFL=40mm 400-1100nm
The LA1304-AB is a 12.7 mm diameter Plano-Convex lens made from N-BK7 Schott glass, sourced from Thorlabs. This lens is designed for use within a broad wavelength range, from 400 to 1100 nanometers, making it a versatile choice for various optical applications.
The lens features an effective focal length (EFL) of 39.9 millimeters, providing a substantial focal point for light convergence. The front surface of the lens is coated with THo AB BAR, a broadband anti-reflection coating that enhances transmission while reducing surface reflections. This coating is also applied to the back surface of the lens.
The lens has a thickness of 1.8 millimeters at the edge and 2.8 millimeters at the center. The curvature of the lens is defined by a radius of 20.6 millimeters on the convex side. The inner and outer radii are both zero, indicating a uniform curvature across the lens surface.
This lens is spherical in shape, with a circular base, and is available for immediate use, as indicated by its "in stock" status on the Thorlabs website. The detailed information provided here is intended to assist users in making informed decisions when selecting optical components for their specific needs.
