This is a G312244525 Plano-Convex Lens, sourced from the renowned optical components manufacturer, Qioptiq Photonics. The lens, which is unmounted and made of fused silica, has a diameter of 50 mm and a thickness at the edge of 1.9 mm, while the thickness at the center is 5.1 mm. The effective focal length (EFL) of this lens is 200 mm, making it suitable for a wide range of optical applications.
The lens is designed to operate within the wavelength range of 725-1050 nm, with a specified wavelength of 355 nm. It features a spherical geometry, with a radius of curvature (R1) of 100 mm. The inner and outer radii are both zero, indicating a plano-convex design.
The lens is coated with Qio Bbar Arb2nirnbk7 on both the front and back surfaces, enhancing its performance and durability. This coating is designed to provide broadband anti-reflection properties, reducing surface reflections and improving transmission efficiency.
