LB1607-B N-BK7 Bi-Convex Lens; Dia:2 in; f=175.0 mm ARC 650-1050nm

The LB1607-B is a high-quality bi-convex lens made from N-BK7 glass, a popular material for optical elements due to its excellent optical properties. This lens, sourced from Thorlabs, features a diameter of 2 inches and a focal length of 175.0 mm, making it suitable for a wide range of applications.

The lens's geometry includes a thickness of 3 mm at the edge and 6.6 mm at the center, with a back focal length of 172.8 mm. The radii of curvature for the front and back surfaces are 179.1 mm and -179.1 mm, respectively. The lens's effective focal length (EFL) is also 175.0 mm.

The LB1607-B is coated with THo BBAR, a broadband anti-reflection coating that reduces reflection across the 650-1050nm wavelength range. This coating enhances the lens's performance in various applications, including imaging, beam shaping, and laser systems.

The lens's shape is spherical, and it is made from n-BK7 Schott, a type of borosilicate glass known for its low dispersion and high transmission in the visible and near-infrared regions. This material makes the lens suitable for use in high-precision optical systems.
