63-640 15mm Dia. x 25mm FL; NIR I Coated; Double-Convex Lens NIR I 600-1050nm
The 63-640 is a high-quality double-convex lens, 15mm in diameter and 25mm in focal length, designed for use in the near-infrared spectrum. This lens is sourced from Edmund Optics, a leading provider of optical components, and is available for immediate purchase.
The lens is made from n-BK7 Schott, a widely used optical glass due to its excellent optical properties and chemical durability. It features a double-convex geometry, with radii of curvature of 25.23mm for the first surface and -25.23mm for the second. This geometry results in a back focal length of 23.82mm and an effective focal length of 25mm.
The lens is coated with EDM NIR-I std curve on both the front and back surfaces. This coating is specifically designed for use in the near-infrared spectrum, providing improved transmission and reduced reflection in this wavelength range. The coating is standard, ensuring consistent performance and reliability.
The lens has a thickness of 1.22mm at the edge and 3.5mm at the center. Despite its compact size, it offers a wide field of view and excellent image quality, making it suitable for a variety of applications.
