G052202525 8 mm Dia. N-BAK4 Mounted Double-Convex Lens; EFL=7mm 725-1050nm
This is the G052202525 lens, a high-quality optical component manufactured by Qioptiq Photonics. It is a spherical lens with a base shape of a circle, designed for use in a wide range of applications. The lens has a diameter of 8 mm and a thickness at the edge of 1.1 mm, while the center thickness measures 3.4 mm.
The lens's effective focal length (EFL) is 7 mm, making it suitable for systems that require a compact, powerful lens. The first radius of curvature (R1) is 7.499 mm, and the second radius of curvature (R2) is -7.499 mm, indicating a double-convex design. The inner and outer radii are both 0, suggesting a symmetrical lens structure.
The lens is made from n-Bak4 Schott, a high-index, low-dispersion optical glass known for its excellent optical properties. It is designed to operate within the wavelength range of 725-1050 nm, making it suitable for near-infrared applications.
The lens features a broadband anti-reflection coating on both the front and back surfaces. This coating, identified as Qio Bbar Arb2nirnbk7, is designed to reduce surface reflections and increase transmission, enhancing the lens's performance in high-light-level applications.
