G314301331 22.4 mm Dia. N-BK7 Plano-Concave Lens; EFL=-40mm
The G314301331 is a plano-concave lens with a diameter of 22.4 mm, sourced from Qioptiq Photonics. This lens is made of N-BK7, a popular optical glass known for its excellent transparency and low auto-fluorescence. The lens's concave shape, with a radius of curvature of -20.833 mm, results in a negative focal length of -40 mm, making it suitable for applications that require light convergence.
The lens has a center thickness of 1.5 mm and features a broadband anti-reflection coating, specifically Qio AL RALVIS AOI 45, on both the front and back surfaces. This coating is designed to minimize surface reflections and increase transmission across the visible spectrum, peaking at 588 nm.
The lens is unmounted, providing flexibility for integration into various optical systems. It is currently in stock and available for purchase through the Qioptiq Photonics website.
