67-621 10mm Dia. x 100mm FL; NIR II Coated; Double-Convex Lens NIR II 750-1550nm
The 67-621 is a high-quality double-convex lens, 10mm in diameter and with a focal length of 100mm, sourced from the renowned optical components vendor, Edmund Optics. This lens is specifically designed for use in the near-infrared (NIR) spectrum, with a coating optimized for the NIR II range of 750-1550nm.
The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The double-convex geometry, with radii of curvature of 102.93mm for both the front and rear surfaces, provides a high degree of focusing power. The lens has an effective focal length (EFL) of 100mm, making it suitable for a wide range of applications.
The lens has a center thickness of 2.5mm and an edge thickness of 2.26mm, providing robustness and durability. The inner and outer radii are both 0mm, indicating a uniform curvature across the lens surface. The lens is coated with Edmund Optics' standard NIR-II coating on both the front and back surfaces, ensuring optimal performance in the NIR II spectrum.
