LA1461-A N-BK7 Plano-Convex Lens; Dia:1 in; f=250.0 mm ARC 350-700nm
The LA1461-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 1 inch (25.4 mm) and a focal length of 250.0 mm, making it suitable for a wide range of applications.
The lens's geometry includes a thickness of 2 mm at the edge and 2.6 mm at the center. The effective focal length (EFL) is 250 mm, and the radius of curvature (ROC) is 128.8 mm. The back focal length (BFL) is 247.4 mm, and both the inner and outer radii are 0 mm.
The LA1461-A is coated with ARC 350-700nm on both the front and back surfaces. This anti-reflection coating reduces unwanted reflections and increases transmission in the 350-700 nm wavelength range, enhancing the lens's performance in various applications.
