49-464 9mm Dia. x 9mm FL; NIR I Coated; Double-Convex Lens NIR I 600-1050nm
The 49-464 is a high-quality double-convex lens, boasting a 9mm diameter and a focal length of 9mm. This lens is sourced from the reputable vendor, Edmund Optics, and is currently in stock. The lens is designed for use within the near-infrared (NIR) spectrum, specifically between 600 and 1050nm, making it suitable for a wide range of applications in this wavelength range.
The lens is constructed from n-SF5 Schott, a material known for its excellent optical properties. It features a standard curve coating on both the front and back surfaces, specifically the EDM NIR-I coating, which is designed to enhance performance within the NIR spectrum. This coating aids in reducing reflection 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 11.38mm for both the front and back surfaces. This shape provides a focused beam of light, making it ideal for imaging or illumination applications. The lens has a central thickness of 3.45mm and an edge thickness of 1.6mm, providing a robust and durable design.
