LA1304-B N-BK7 Plano-Convex Lens; Dia:0.5 in; f=40.0 mm ARC 650-1050nm

The LA1304-B 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 and versatility. The lens's geometry includes a thickness of 1.8 mm at the edge and 2.8 mm at the center, providing a solid structure for reliable performance.

The LA1304-B features an Anti-Reflection coating, specifically designed for the wavelength range of 650-1050nm, enhancing its transmission capabilities within this spectrum. This coating, denoted as 'tho b bbar', is applied to both the front and back surfaces of the lens, ensuring optimal light transmission and minimal reflection.

The lens's shape is spherical, a common design for Plano-Convex lenses, which allows for a wide range of applications, including but not limited to, imaging, beam shaping, and laser systems. The curvature of the lens is defined by a radius of 20.6 mm on the planar side and a back focal length of 38 mm.
