G311339525 31.5 mm Dia. N-BK7 Double-Convex Lens; EFL=40mm 725-1050nm
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 40 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 particularly suitable for use in the visible and near-infrared spectrum, with a wavelength range of 725-1050 nm.
The lens features a double-convex geometry, with radii of curvature of 41.867 mm on both sides. This design provides a high level of optical power, making the lens ideal for use in focusing or imaging applications.
The lens has a thickness of 2.1 mm at the edge and 8.3 mm at the center. This robust construction ensures the lens can withstand the rigors of regular use, while also minimizing the risk of optical distortions caused by mechanical stress.
The lens is coated with a broadband anti-reflection coating, which reduces surface reflections and increases transmission. The coating is applied to both the front and back surfaces of the lens, ensuring optimal performance in both transmission and reflection.
