LB1406-A N-BK7 Bi-Convex Lens; Dia:6.0 mm; f=12.0 mm ARC 350-700nm
The LB1406-A is a high-quality bi-convex lens from Thorlabs, designed with a diameter of 6.0 mm and a focal length of 12.0 mm. This lens is fabricated from N-BK7, a popular glass type in the Schott catalog, known for its excellent optical properties.
The lens features an antireflection coating, denoted as "tho a bbar," which is applied to both the front and back surfaces. This coating is designed to operate within the 350-700nm wavelength range, making it suitable for a wide array of applications, particularly those involving visible light.
The geometry of the LB1406-A includes a thickness of 1.5 mm at the edge and 2.3 mm at the center. The lens's effective focal length (EFL) is 12.0 mm, while the back focal length (BFL) is 11.2 mm. The radii of curvature for the first and second surfaces are 12.0 mm and -12.0 mm, respectively.
This lens is spherical in shape and circular in base form. It is currently in stock and available for immediate purchase from the Thorlabs website. The detailed specifications and additional product information can be found at https://www.thorlabs.com/thorproduct.cfm?partnumber=LB1406-A.
