This item is a high-quality double-convex lens, designed and manufactured by MKS/Newport, a renowned vendor in the optical industry. The lens boasts a diameter of 25.4 mm and a focal length of 250 mm, making it suitable for a wide range of applications.
The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. It features a double-convex geometry, with radii of curvature of 257.789 mm for both the front and back surfaces. This geometry provides a high degree of focusing power and a large numerical aperture, making it ideal for use in laser systems and other high-precision applications.
The lens is coated with New AR-33, a broadband anti-reflective coating designed for use in the visible and near-infrared regions. This coating significantly reduces surface reflections, improving transmission and enhancing the performance of the lens in its intended application.
The lens has a thickness of 3 mm at the edge and 3.626 mm at the center, providing excellent mechanical stability and resistance to deformation. The inner and outer radii are both 0 mm, indicating a uniform curvature across the lens surface.
