LA1779-B N-BK7 Plano-Convex Lens; Dia:2 in; f=1000.0 mm ARC 650-1050nm
The LA1779-B N-BK7 Plano-Convex Lens is a high-quality optical component sourced from Thorlabs, a leading vendor in the field of optical equipment. This lens, with a diameter of 2 inches, is designed for use in a wide range of optical systems, offering a focal length of 1000.0 mm and a shape that is both spherical and plano-convex.
The lens is made from N-BK7, a type of glass commonly used in optical applications due to its excellent optical properties. The base shape of the lens is circular, with a thickness at the edge of 3 mm and a center thickness of 3.6 mm. The effective focal length (EFL) of the lens is 1000.0 mm, and the radius of curvature (R1) is 515.1 mm. The back focal length (BFL) is 994.3 mm, and the lens does not have an inner or outer radius.
The LA1779-B lens is coated with a broadband anti-reflection coating (ARC) that is designed to work in the 650-1050nm wavelength range. This coating helps to reduce surface reflections, thereby improving the overall efficiency and performance of the lens. The coating is applied to both the front and back surfaces of the lens.
In terms of availability, the LA1779-B N-BK7 Plano-Convex Lens is currently in stock, according to the vendor's website. This information is subject to change, so it's always a good idea to check the vendor's website for the most up-to-date status.
