LA1380-A N-BK7 Plano-Convex Lens; Dia:2 in; f=500.0 mm ARC 350-700nm
The LA1380-A is a plano-convex lens made of 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 500.0 mm. The lens's design, with a spherical shape and a single curved surface, is ideal for a wide range of applications.
The lens's geometry includes a thickness of 3 mm at the edge and 4.3 mm at the center. The effective focal length (EFL) is 500 mm, and the back focal length (BFL) is 495.5 mm. The lens's inner and outer radii are both 0, indicating a plano surface on one side and a curved surface on the other.
The LA1380-A is coated with ARC 350-700nm, a broadband anti-reflection coating that reduces reflection across the visible spectrum (350-700 nm). This coating enhances the lens's performance by increasing transmission and reducing unwanted reflections.
This lens is suitable for use in various applications, including imaging systems, beam shaping, and laser applications. With its high-quality N-BK7 glass, precise geometry, and broadband anti-reflection coating, the LA1380-A is a reliable and versatile optical component.
