LA1727-A N-BK7 Plano-Convex Lens; Dia:2 in; f=750.0 mm ARC 350-700nm
The LA1727-A is a high-quality plano-convex lens from Thorlabs, designed for use in a wide range of optical applications. This lens is fabricated from N-BK7, a popular glass type known for its excellent optical properties, making it an ideal choice for applications that require high-performance optics.
The lens features a diameter of 2 inches (50.8 mm) and a focal length of 750.0 mm, providing a large enough working distance for many setups. The plano-convex design, where one side is flat and the other is curved, offers a number of advantages, including a wide field of view and low spherical aberration.
The LA1727-A is coated with Thorlabs' AR coating, which is designed to reduce reflection and increase transmission in the 350-700 nm range. This coating enhances the lens's performance in applications that require high transmission, such as imaging and laser systems.
The lens has a thickness of 3 mm at the edge and 3.8 mm at the center, providing a robust and durable design. The inner and outer radii are both 0, indicating a sharp curvature on the convex side.
