G312259525 18 mm Dia. UVFS Plano-Convex Lens; EFL=30mm 725-1050nm
The G312259525 is a Plano-Convex lens, part of the extensive catalog of optical elements sourced from Qioptiq Photonics. This lens, with a diameter of 18 mm, is designed for use in the ultraviolet to near-infrared spectrum, specifically between 725 and 1050 nanometers.
The lens features an effective focal length (EFL) of 30 mm, making it suitable for a wide range of optical applications. The plano-convex geometry, where one side is flat and the other is curved, allows for efficient light collection and focusing. The lens has a center thickness of 4.4 mm and an edge thickness of 1.5 mm, providing a robust and durable structure.
The lens is made from UVFS (UV Fused Silica), a high-purity silica glass known for its excellent transmission properties in the UV and NIR regions. This material also offers high resistance to thermal shock and radiation damage, making it ideal for use in harsh environments.
The lens is coated with Qio Bbar Arb2nirnbk7 on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, thereby improving overall system efficiency.
