G314422322 22.4 mm Dia. UVFS Plano-Concave Lens; EFL=-50mm 450-700nm
The G314422322 is a plano-concave lens with a diameter of 22.4 mm, sourced from the renowned optical components vendor, Qioptiq Photonics. This lens is designed for use in the ultraviolet to near-infrared spectrum, specifically between 450 and 700 nm.
The lens features a negative focal length (EFL) of -50 mm, making it suitable for applications that require light convergence or divergence. The plano-concave geometry, characterized by a flat front surface and a curved back surface, contributes to its unique optical properties.
The lens is made from UVFS (UltraViolet Fused Silica) material, identified as UVFS Mal- 1965 in the material database. This material is known for its excellent transparency in the UV region and its high resistance to thermal shock and chemical etching.
The lens's front and back surfaces are coated with Qio Bbar Arb2visnbk7, a broadband anti-reflection coating designed for use in the visible and near-infrared regions. This coating reduces surface reflections, enhancing the lens's transmission efficiency and overall performance.
The lens's geometry includes a center thickness of 1.5 mm and a radius of curvature of -25.483 mm for the curved back surface. The lens is unmounted, offering users the flexibility to integrate it into their optical systems according to their specific requirements.
