This is a high-quality Plano-Convex lens from Qioptiq Photonics, designed for precision optical applications. The lens has a diameter of 12.7 mm and a focal length (EFL) of 500mm, making it suitable for use in systems where a long focal length is required.
The lens is made from N-BK7 glass, a popular choice in the optical industry due to its excellent optical properties and high damage threshold. The lens has a spherical shape, with a radius of curvature (R1) of 260.39 mm on the convex side. The lens is mounted, with a thickness of 2.9 mm at the edge and 3 mm at the center.
The lens is coated with Qio Bbar Arb2nirnbk7 on both the front and back surfaces. This coating is designed to reduce reflection and increase transmission, enhancing the performance of the lens in the 725-1050nm wavelength range.
The lens is available for purchase from the Qioptiq Photonics website, where it is listed as being in stock. The website also provides further technical details and specifications for the lens.
