G314315331 22.4 mm Dia. N-BK7 Plano-Concave Lens; EFL=-50mm
The G314315331 is a 22.4 mm diameter Plano-Concave lens, manufactured by Qioptiq Photonics. This lens is made of N-BK7, a popular optical glass type known for its excellent optical properties and versatility. The lens features a negative focal length (EFL) of -50mm, making it suitable for applications that require light convergence or divergence.
The lens's geometry includes a center thickness of 1.5mm, with no inner or outer radius specified, indicating a simple plano-concave design. The concave surface of the lens is defined by a radius of curvature of -26.039mm.
The lens is coated with Qio AL RALVIS AOI 45 on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and improving transmission, particularly at the specified wavelength of 588nm.
