LA1779-C N-BK7 Plano-Convex Lens; Dia:2 in; f=1000.0 mm ARC 1050-1700nm

The LA1779-C is a plano-convex lens with a diameter of 2 inches, designed for use in the 1050-1700nm wavelength range. This lens is sourced from Thorlabs, a reputable vendor known for its high-quality optical components.

The lens is made from N-BK7, a popular glass type in the optical industry due to its excellent optical properties. It has a focal length of 1000.0 mm, making it suitable for a wide range of applications that require long focal lengths.

The geometry of the lens includes a thickness of 3 mm at the edge and 3.6 mm at the center. The inner radius is 0, while the outer radius is also 0, indicating a flat surface on one side and a curved surface on the other. The radius of curvature of the curved surface is 515.1 mm, and the back focal length is 994.3 mm.

The LA1779-C is coated with a broadband anti-reflection coating (tho c bbar) on both the front and back surfaces. This coating is designed to reduce reflection and increase transmission across the specified wavelength range, enhancing the lens's performance in various applications.
