LB1092-B N-BK7 Bi-Convex Lens; Dia:0.5 in; f=15.0 mm ARC 650-1050nm

The LB1092-B is a high-quality bi-convex lens, designed and manufactured by Thorlabs, a leading global supplier of photonics equipment. This lens, with a diameter of 0.5 inches and a focal length of 15.0 mm, is made from N-BK7, a popular glass type known for its excellent optical properties.

The lens features a base shape of a circle, with a geometry that includes a diameter of 12.7 mm, a thickness at the edge of 1.8 mm, and a thickness at the center of 4.7 mm. The effective focal length (EFL) is 15 mm, and the back focal length (BFL) is 13.4 mm. The radii of curvature for the first and second surfaces are 14.6 mm and -14.6 mm, respectively.

The LB1092-B is coated with a broadband anti-reflection coating (ARC), designed to operate between 650-1050 nm. This coating reduces surface reflections, thereby increasing transmission and improving overall lens performance. The lens is designed for use in a wide range of applications, including but not limited to, beam shaping, focusing, and collimation.

The lens is available for immediate purchase and shipping, as indicated by its "in stock" status on the Thorlabs website. With its superior optical performance, robust design, and wide operational wavelength range, the LB1092-B is an excellent choice for any application requiring a high-performance bi-convex lens.
