LA1725-B N-BK7 Plano-Convex Lens; Dia:2 in; f=400.0 mm ARC 650-1050nm
The LA1725-B is a plano-convex lens made from N-BK7 glass, a popular material in the optical industry due to its excellent optical properties. This lens, sourced from Thorlabs, has a diameter of 2 inches (50.8 mm) and a focal length of 400.0 mm. The lens's design, with a spherical shape and a plano-convex base, allows for efficient light collection and focusing.
The lens's geometry includes a thickness of 3 mm at the edge and 4.6 mm at the center, providing a solid structure for various applications. The effective focal length (EFL) is 400 mm, which, combined with the lens's diameter, allows for a wide field of view. The lens's front and back surfaces are coated with ARC 650-1050nm, a broadband anti-reflection coating that reduces surface reflections and increases transmission in the spectral range of 650-1050 nm.
This lens is suitable for use in a variety of applications, including imaging systems, beam shaping, and laser applications. Its high-quality materials and precise construction ensure reliable performance and durability. The lens's availability from Thorlabs, a reputable vendor in the optical industry, further guarantees its quality and reliability.
