The LA1509-A 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 100.0 mm. The lens's design includes an antireflection coating (ARC) optimized for the 350-700nm wavelength range, which enhances its transmission capabilities and reduces unwanted reflections.
The lens's geometry is characterized by its edge thickness of 2 mm and center thickness of 3.6 mm. The front surface has a radius of curvature (R1) of 51.5 mm, while the back focal length (BFL) is 97.3 mm. The lens's effective focal length (EFL) is 100 mm, which is the distance from the lens's principal point to the focal point. The lens's shape is spherical, and it has no inner or outer radius.
This lens is suitable for various applications, including imaging, beam shaping, and laser systems. Its high-quality N-BK7 glass and precise manufacturing ensure excellent optical performance, making it a reliable choice for various optical setups.
