LA1986-B N-BK7 Plano-Convex Lens; Dia:1 in; f=125.0 mm ARC 650-1050nm
The LA1986-B 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 Schott glass, a popular material known for its excellent optical properties and versatility.
The lens has a diameter of 1 inch (25.4 mm) and a focal length of 125.0 mm, making it suitable for applications that require a long focal length. The plano-convex design, where one side is flat and the other is curved, allows for efficient light collection and focusing.
The LA1986-B features an antireflection coating, specifically the Thorlabs Broadband AR Coating (650-1050nm), which is designed to minimize surface reflections and increase transmission in the specified wavelength range. This coating is applied to both the front and back surfaces of the lens.
The lens has a central thickness of 3.3 mm and an edge thickness of 2 mm, providing structural integrity and resistance to optical distortions. The inner and outer radii are 0 mm, indicating a sharp curvature on the convex side.
This lens is a great choice for applications that require a long focal length, high transmission, and minimal surface reflections. It is available for purchase directly from Thorlabs, as indicated by the "weblink status" field in the item data.
