49-484 15mm Dia. x 50mm FL; NIR I Coated; Double-Convex Lens NIR I 600-1050nm
The 49-484 is a high-quality double-convex lens, 15mm in diameter and with a focal length of 50mm, sourced from the renowned optical components vendor, Edmund Optics. This lens is specifically designed for use within the near-infrared (NIR) spectrum, with a coating optimized for the 600-1050nm range, making it an ideal choice for applications such as thermal imaging, spectroscopy, and other NIR-based technologies.
The lens is fabricated from N-BK7 Schott glass, a material well-known for its excellent optical properties, including high transmittance and low auto-fluorescence. The double-convex geometry, with radii of curvature of 51.16mm for both the front and rear surfaces, ensures a wide field of view and low distortion, making it suitable for imaging applications.
The lens features a standard anti-reflection coating, Edmund Optics' NIR I coating, on both the front and rear surfaces. This coating is designed to minimize surface reflections and increase transmission within the specified NIR range. The lens has an edge thickness of 1.9mm and a center thickness of 3mm, providing robustness and durability.
