G312006400 4 mm Dia. N-BK7 Plano-Convex Lens; EFL=4mm
The G312006400 is a 4 mm diameter Plano-Convex lens, designed and manufactured by Qioptiq Photonics. This lens boasts an effective focal length (EFL) of 4mm, making it suitable for a wide range of optical applications.
The lens is made from N-BK7, a popular optical glass known for its excellent optical properties. The Plano-Convex geometry, where one side is flat and the other is curved, allows for efficient light gathering and focusing. The lens has a thickness of 0.45mm at the edge and 2mm at the center, providing a robust structure while maintaining high optical performance.
The G312006400 lens features a silver coating on both the front and back surfaces, identified as 'qio silver ragv 45'. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, thereby improving the overall efficiency of the optical system.
The lens is currently in stock and can be purchased directly from the Qioptiq Photonics website. For more detailed information, including technical specifications and purchasing options, please refer to the provided weblink.
