89-239 12mm Dia. x 12mm FL; YAG-BBAR Coated; Double-Convex Lens YAG-BBAR 500-1100nm
This is a high-quality double-convex lens from the renowned optical components manufacturer, Edmund Optics. The lens, with the product code 89-239, is a spherical lens featuring a circular base shape and a diameter of 12mm. The lens's design includes a thickness of 1.41mm at the edge and 3.85mm at the center, with an effective focal length (EFL) of 12mm.
The lens's curvature is defined by two radii: the first radius (R1) measures 15.34mm, while the second radius (R2) measures -15.34mm, indicating a double-convex shape. The back focal length (BFL) of the lens is 10.79mm. The lens is made from the high-quality material n-SF5 from Schott, ensuring durability and excellent optical performance.
The lens is coated with YAG-BBAR, a proprietary coating from Edmund Optics, designed to enhance its performance within the wavelength range of 500-1100nm. This coating improves the lens's transmission and reduces reflection, making it ideal for various applications, including imaging, beam shaping, and laser systems.
The lens is currently in stock and can be purchased directly from the Edmund Optics website using the provided weblink.
