LB1106-A N-BK7 Bi-Convex Lens; Dia:2 in; f=125.0 mm ARC 350-700nm

The LB1106-A is a high-quality bi-convex lens from Thorlabs, designed for use in a wide range of optical applications. This lens is made from N-BK7, a popular glass type known for its excellent optical properties, and is manufactured to rigorous specifications to ensure high performance.

The lens has a diameter of 2 inches (50.8 mm) and a focal length of 125.0 mm, making it suitable for use in systems where a long focal length is required. The lens is also AR-coated for the 350-700nm wavelength range, which helps to reduce surface reflections and improve transmission.

The geometry of the lens is carefully controlled to ensure excellent image quality. The lens has a center thickness of 8.1 mm and edge thickness of 3 mm, which helps to minimize optical aberrations. The lens also has a high degree of symmetry, with both surfaces having the same radius of curvature (127.4 mm), which further contributes to its excellent optical performance.

The lens is designed to be used in a variety of applications, including imaging, beam shaping, and laser applications. Its high quality and excellent optical properties make it an ideal choice for researchers and engineers who require a reliable and high-performance lens.
