LB1471-B N-BK7 Bi-Convex Lens; Dia:1 in; f=50.0 mm ARC 650-1050nm

The LB1471-B is a high-quality bi-convex lens, designed and manufactured by Thorlabs. This lens is made from N-BK7, a popular glass type in the optical industry, known for its excellent optical properties and versatility. The lens has a diameter of 1 inch (25.4 mm) and a focal length of 50.0 mm, making it suitable for a wide range of applications.

The lens geometry is characterized by its spherical shape, with both surfaces curved outwards. The first surface has a radius of curvature of 50.6 mm, while the second surface has a radius of -50.6 mm. This bi-convex design helps to minimize spherical aberration, ensuring high-quality imaging and light transmission.

The lens has a thickness of 2 mm at the edge and 5.2 mm at the center. The effective focal length (EFL) is 50 mm, and the back focal length (BFL) is 48.2 mm. The lens is coated with a broadband anti-reflection coating, designed to operate in the spectral range of 650-1050 nm. This coating helps to reduce surface reflections, improving the overall transmission of the lens.
