G311335329 31.5 mm Dia. N-BK7 Double-Convex Lens; EFL=130mm 1064nm
This is a high-quality double-convex lens from Qioptiq Photonics, designed for precision optical applications. The lens has a diameter of 31.5 mm and a focal length of 130 mm, making it suitable for a wide range of uses.
The lens is made from N-BK7, a type of borosilicate glass known for its excellent optical properties. This material is often used in high-precision applications due to its low dispersion and high transmission in the visible and near-infrared regions.
The lens features a double-convex geometry, with radii of curvature of 134.325 mm on both sides. This design provides a large numerical aperture, making it ideal for imaging applications. The lens has a center thickness of 4 mm and an edge thickness of 2.2 mm, providing robustness and stability.
The lens is coated with Qio HP Nbar ARHS-YAG on both the front and back surfaces. This coating reduces reflection and increases transmission, enhancing the performance of the lens in high-power laser applications.
The lens is currently in stock and can be purchased directly from the Qioptiq Photonics website. It is a versatile and reliable option for any application that requires a high-quality double-convex lens.
