LA1401-A N-BK7 Plano-Convex Lens; Dia:2 in; f=60.0 mm ARC 350-700nm
The LA1401-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, a popular glass type known for its excellent optical properties, and features a diameter of 2 inches (50.8 mm) and a focal length of 60.0 mm.
The lens has a clear aperture of 50.8 mm, providing a wide field of view, and a thickness of 3 mm at the edge, increasing to 16.3 mm at the center. This design, combined with the N-BK7 glass, results in an effective focal length (EFL) of 60 mm and a back focal length (BFL) of 49.1 mm. The inner radius of the lens is 0 mm, while the outer radius is also 0 mm, indicating a flat surface on the non-curved side.
The LA1401-A is coated with Thorlabs' AR coating, which is designed to reduce reflection over the 350-700 nm range. This coating ensures high transmission and low loss, making the lens ideal for use in laser applications and other settings where high light levels are required.
