63-630 5mm Dia. x 25mm FL; NIR I Coated; Double-Convex Lens NIR I 600-1050nm

The 63-630 is a high-quality double-convex lens, 5mm in diameter and with a focal length of 25mm, 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 ideal for a wide array of applications within this wavelength band.

The lens is constructed 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 25.58mm and -25.58mm, 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, on both the front and back surfaces. This coating is designed to minimize surface reflections and increase transmission within the NIR range, further enhancing the lens' performance in its intended application.

The lens has a central thickness of 1.5mm and an edge thickness of 1.26mm, providing robustness and durability while maintaining a compact and lightweight design. The back focal length (BFL) is 24.5mm, which should be considered when integrating this lens into optical systems.
