49-481 15mm Dia. x 15mm FL; NIR I Coated; Double-Convex Lens NIR I 600-1050nm

The 49-481 is a high-quality double-convex lens, 15mm in diameter and featuring a focal length of 15mm. This lens is sourced from the reputable optical vendor, Edmund Optics, and is currently in stock. It is designed for use within the near-infrared 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-SF11 Schott, a high-index glass material known for its excellent optical properties. This material, combined with the double-convex geometry, enables the lens to deliver superior performance in terms of image quality, light transmission, and chromatic correction. The lens has an inner radius of 0mm and an outer radius of 0mm, further enhancing its optical capabilities.

The 49-481 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 optimize the lens' performance within the near-infrared spectrum. It enhances the lens' durability, resistance to environmental factors, and overall optical efficiency.

The geometry of the lens includes a thickness of 1.93mm at the edge and 4.5mm at the center. The back focal length (BFL) is 13.68mm, and the effective focal length (EFL) is 15mm. These parameters, along with the lens' high-quality construction and coating, make the 49-481 an excellent choice for various optical applications within the near-infrared spectrum.
