LA1131-B N-BK7 Plano-Convex Lens; Dia:1 in; f=50.0 mm ARC 650-1050nm
The LA1131-B is a Plano-Convex lens, a type of spherical lens, sourced from the reputable optical components manufacturer, Thorlabs. This lens is designed with a circular base shape and features a diameter of 1 inch (25.4 mm) and a focal length of 50.0 mm. The lens's geometry includes a thickness of 2 mm at the edge and 5.3 mm at the center, with an effective focal length (EFL) of 50 mm.
The lens is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties. The lens's front and back surfaces are coated with a broadband anti-reflection coating (ARC), designed to operate within the wavelength range of 650-1050 nm. This coating helps reduce surface reflections, thereby increasing the lens's transmission efficiency.
The LA1131-B is available from Thorlabs and is currently in stock, according to the vendor's website. This lens is a versatile optical component, suitable for a wide range of applications, including but not limited to, imaging systems, beam shaping, and laser applications.
