G311333525 31.5 mm Dia. N-BK7 Double-Convex Lens; EFL=100mm 725-1050nm

The G311333525 is a high-quality double-convex lens, sourced from the renowned optical components manufacturer, Qioptiq Photonics. This lens, with a diameter of 31.5 mm, is designed for use in the 725-1050nm wavelength range, making it suitable for a wide array of applications in the optical spectrum.

The lens is made from N-BK7, a popular glass type known for its excellent optical properties. This material, also known as Schott glass, is characterized by a high refractive index and low dispersion, making it an ideal choice for many optical applications. The lens features a double-convex geometry, with radii of curvature of 102.92 mm for both the front and back surfaces. This geometry is designed to provide a high level of optical performance, with a focal length of 100 mm.

The lens has a thickness of 2.4 mm at the edge and 4.8 mm at the center, providing a robust and durable structure. The lens is coated with Qio Bbar Arb2nirnbk7 on both the front and back surfaces, enhancing its performance in the specified wavelength range. This coating reduces reflection and increases transmission, thereby improving the overall efficiency of the optical system in which the lens is used.
