G052118331 12.7 mm Dia. N-BK7 Mounted Plano-Convex Lens; EFL=500mm
The G052118331 is a mounted plano-convex lens, part of Qioptiq Photonics' extensive catalog of precision optics. This lens boasts a 12.7 mm diameter and a focal length of 500mm, making it suitable for a wide range of applications.
The lens is made from N-BK7, a popular glass type known for its excellent optical properties. The plano-convex geometry, where one side is flat and the other is curved, allows for efficient light collection and focusing. The lens has a thickness of 2.9mm at the edge and 3mm at the center, providing a robust structure while maintaining a sleek profile.
The lens is coated with Qio AL RALVIS AOI 45 on both the front and back surfaces. This anti-reflection coating reduces unwanted reflections and increases transmission, enhancing the overall performance of the lens. The coating is designed for a central wavelength of 588nm, making it suitable for applications in the yellow-orange part of the spectrum.
The item data also provides information about the lens's inner and outer radii, which are both 0 in this case. This indicates that the lens has a simple plano-convex design without any additional curvatures or features.
