G311384331 12.7 mm Dia. N-BK7 Double-Convex Lens; EFL=50mm
The G311384331 is a 12.7 mm diameter Double-Convex lens, manufactured by Qioptiq Photonics. This lens, designed for use in the visible light spectrum, has an effective focal length (EFL) of 50mm, making it suitable for a wide range of optical applications.
The lens is made from N-BK7, a high-quality borosilicate glass known for its excellent optical properties. This is evident in the lens's geometry, which features a thickness of 2.2mm at the edge and 3mm at the center, providing a robust structure while maintaining high optical performance.
The G311384331 lens features a double-convex shape, with radii of curvature of 51.08mm for both the front and back surfaces. This shape is designed to minimize spherical aberration, ensuring that the lens focuses light accurately and efficiently. The lens's inner and outer radii are 0, indicating a symmetrical design.
The lens is coated with Qio AL RALVIS AOI 45 on both the front and back surfaces. This anti-reflection coating reduces surface reflections, improving light transmission and enhancing the lens's overall performance.
