45-884 18mm Dia. x 36mm FL; VIS-NIR Coated; Double-Convex Lens VIS-NIR 400-1000nm
The 45-884 is a high-quality double-convex lens, 18mm in diameter and 36mm in focal length, sourced from the renowned optical components manufacturer, Edmund Optics. This lens is specifically designed for use within the visible to near-infrared spectrum, spanning 400 to 1000nm, making it suitable for a wide range of optical applications.
The lens is crafted from Schott's n-BK7 glass, a material well-known for its excellent optical properties, including a high Abbe number and low dispersion. This ensures minimal chromatic aberration, delivering sharp and clear images. The lens features a double-convex geometry, with radii of curvature of 36.6mm and -36.6mm for the front and back surfaces, respectively. This geometry provides a large field of view and excellent image quality.
The 45-884 lens comes with a broadband anti-reflection coating, denoted as 'edm visnir0sp2002000', on both the front and back surfaces. This coating is designed to reduce surface reflections and increase transmission within the specified spectral range, further enhancing the lens's performance.
