LB1406-B N-BK7 Bi-Convex Lens; Dia:6.0 mm; f=12.0 mm ARC 650-1050nm
The LB1406-B is a high-quality bi-convex lens from Thorlabs, featuring a diameter of 6.0 mm and a focal length of 12.0 mm. This lens is made from N-BK7, a popular glass type in the optical industry due to its excellent optical properties. The lens's geometry includes a thickness of 1.5 mm at the edge and 2.3 mm at the center, with a back focal length of 11.2 mm.
This lens is designed for use in the 633 nm wavelength range and features broadband anti-reflection coatings (ARC) on both the front and back surfaces, optimized for the 650-1050 nm range. These coatings are crucial for minimizing surface reflections and enhancing overall transmission, making this lens ideal for various applications, including laser systems and optical imaging.
The LB1406-B's bi-convex shape, where both surfaces are convex, provides excellent focusing capabilities. This shape is often used in optical systems where a high level of focusing is required. The lens's spherical geometry ensures that light rays passing through the lens are focused to a single point, making this lens suitable for a wide range of applications.
