LA1484-B N-BK7 Plano-Convex Lens; Dia:1 in; f=300.0 mm ARC 650-1050nm
The LA1484-B is a plano-convex lens made from 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 300 mm. The lens's geometry includes a thickness of 2 mm at the edge and 2.5 mm at the center, providing a balanced structure for various applications.
The lens's effective focal length (EFL) is 300 mm, which is the distance from the lens's center to the focal point. The front radius of curvature (R1) is 154.5 mm, and the back focal length (BFL) is 297.3 mm. The lens's inner and outer radii are both 0, indicating a flat surface on the opposite side of the curved face.
The LA1484-B is coated with a broadband anti-reflection coating (ARC) suitable for wavelengths between 650 and 1050 nm. This coating reduces unwanted reflections and increases transmission, enhancing the lens's performance in its intended application.
