LA1304-A N-BK7 Plano-Convex Lens; Dia:0.5 in; f=40.0 mm ARC 350-700nm

The LA1304-A is a high-quality Plano-Convex lens, sourced from the reputable optical components manufacturer, Thorlabs. This lens boasts a diameter of 0.5 inches (12.7 mm) and a focal length of 40.0 mm, making it suitable for a wide range of optical applications.

The lens is crafted from N-BK7, a popular glass type in the optical industry, known for its excellent optical properties. The Plano-Convex geometry, where one side is flat and the other is curved, allows for efficient light collection and focusing. The lens has a center thickness of 2.8 mm and an edge thickness of 1.8 mm, providing robustness and durability.

The LA1304-A features an Anti-Reflection coating on both the front and back surfaces, optimized for the ARC 350-700nm range. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission and improving overall system efficiency.

The curvature of the lens is defined by a radius of 20.6 mm on the curved side, and the back focal length is 38 mm. The lens has no inner or outer radius, indicating a uniform thickness across the lens.
