G314424525 22.4 mm Dia. UVFS Plano-Concave Lens; EFL=-150mm 725-1050nm
This is the G314424525 model from Qioptiq Photonics, a 22.4 mm diameter Plano-Concave Lens made of UVFS material with a unique refractive index. The lens is unmounted and features a fused silica construction, ensuring high optical quality and durability.
The lens has an effective focal length (EFL) of -150mm, indicating its diverging nature. This makes it suitable for applications where beam expansion is required. The lens's concave shape, characterized by a radius of curvature (R1) of -75.531mm, contributes to its diverging properties.
The lens is designed to operate within the wavelength range of 725-1050nm, making it suitable for near-infrared (NIR) applications. It comes with a broadband anti-reflection coating, specifically the Qio Bbar Arb2nirnbk7 coating, on both the front and back surfaces. This coating enhances the lens's transmission efficiency and reduces surface reflections, thereby improving overall system performance.
