G311213525 22.4 mm Dia. UVFS Double-Convex Lens; EFL=200mm 725-1050nm
This is a G311213525 double-convex lens, sourced from the renowned optical components manufacturer, Qioptiq Photonics. The lens, which is unmounted, features a fused silica material (UVFS) with a diameter of 22.4 mm and a double-convex geometry. The lens has a center thickness of 2.2 mm and an edge thickness of 1.6 mm, providing a robust structure for various applications.
The lens has an effective focal length (EFL) of 200 mm, making it suitable for applications that require a longer focal length. The radii of curvature for the first and second surfaces are 199.53 mm and -199.53 mm, respectively, indicating a symmetric convex-convex design. The lens does not have an inner or outer radius, suggesting a continuous curvature from edge to edge.
The lens is designed to operate within the wavelength range of 355 nm. It comes with a front and back coating of Qio Bbar Arb2nirnbk7, which is a broadband anti-reflection coating. This coating is designed to reduce surface reflections and increase transmission, making the lens more efficient in various applications.
