G311329525 8 mm Dia. N-BAK4 Double-Convex Lens; EFL=7mm 725-1050nm
This is a G311329525 lens, a high-quality optical component sourced from Qioptiq Photonics. It is a spherical lens with a base shape of a circle, designed for use in a wide range of optical applications. The lens has a diameter of 8 mm and a thickness at the edge of 1.1 mm, while the center thickness is 3.4 mm. The effective focal length (EFL) of this lens is 7 mm, making it suitable for systems that require a compact, powerful lens.
The lens is made from N-BAK4, a type of glass known for its excellent optical properties. This material is particularly suitable for use in the visible and near-infrared spectrum, with a wavelength of 587.6 nm. The lens features a double-convex geometry, with radii of curvature of 7.499 mm on both sides. This geometry is designed to provide a high level of optical performance, with minimal distortion and excellent image quality.
The lens is coated with a Qio Bbar Arb2nirnbk7 coating on both the front and back surfaces. This coating is designed to reduce reflection and improve transmission, enhancing the overall performance of the lens. The lens is available from the Qioptiq Photonics website, where it is listed as being in stock.
