63-629 5mm Dia. x 20mm FL; NIR I Coated; Double-Convex Lens NIR I 600-1050nm
The 63-629 is a high-quality double-convex lens, boasting a 5mm diameter and a focal length of 20mm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is available in stock for immediate use. The lens is designed for use within the near-infrared (NIR) spectrum, specifically between 600 and 1050nm, making it ideal for a wide range of applications within this spectrum.
The lens is constructed from Schott's n-BK7 glass, a material well-known for its excellent optical properties, including a high Abbe number and low dispersion. This makes the lens particularly suitable for applications requiring high image quality and color correction.
The 63-629 lens features a standard coating on both the front and back surfaces. This coating, identified as 'edm nir-i std curve', is specifically designed to enhance the lens' performance within the NIR spectrum. It aids in reducing surface reflections and increasing transmission, thereby improving the overall efficiency and quality of the optical system in which it is used.
The lens geometry is characterized by its double-convex shape, with radii of curvature of 20.41mm on both the front and back surfaces. This shape provides a high degree of focusing power, making the lens suitable for use in a variety of optical systems, including cameras, microscopes, and spectrometers.
