G311206525 18 mm Dia. UVFS Double-Convex Lens; EFL=20mm 725-1050nm
This is the G311206525 model from Qioptiq Photonics, a high-quality double-convex lens with a diameter of 18 mm. The lens is designed for use in the ultraviolet to near-infrared spectrum, specifically between 725 and 1050 nanometers.
The lens features a focal length of 20 mm (EFL), making it suitable for a wide range of optical applications. The base shape is circular, and the lens is spherical, with a first radius (R1) of 19.668 and a second radius (R2) of -19.668. This symmetrical design ensures excellent image quality and minimal distortion.
The lens is made from UVFS (mal- 1965), a material known for its high transparency and excellent optical properties in the UV and NIR ranges. The lens has a thickness of 1.4 mm at the edge and 5.8 mm at the center, providing robustness and stability.
The G311206525 model comes with a broadband anti-reflection coating on both the front and back surfaces. This coating, identified as Qio Bbar Arb2nirnbk7, significantly reduces surface reflections and increases transmission, ensuring optimal performance in various lighting conditions.
