LB1607-C N-BK7 Bi-Convex Lens; Dia:2 in; f=175.0 mm ARC 1050-1700nm
The LB1607-C is a high-quality bi-convex lens made from N-BK7 glass, a popular material for its excellent optical properties and versatility. 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 optical applications.
The lens geometry includes a thickness of 3 mm at the edge and 14.4 mm at the center, with a back focal length of 172.8 mm. The radii of curvature for the first and second surfaces are 179.1 mm and -179.1 mm, respectively. The lens is designed to operate at a wavelength of 633 nm.
The LB1607-C is coated with a broadband anti-reflection coating, specifically designed for the 1050-1700 nm range. This coating reduces surface reflections, thereby increasing transmission and improving overall system performance. The lens shape is spherical, a common choice for its ease of manufacturing and good imaging quality.
