49-479 12mm Dia. x 48mm FL; NIR I Coated; Double-Convex Lens NIR I 600-1050nm

The 49-479 is a high-quality double-convex lens, 12mm in diameter and 48mm in focal length, sourced from the renowned optical components vendor, Edmund Optics. This lens is designed for use within the near-infrared (NIR) spectrum, specifically between 600 and 1050 nanometers, making it suitable for a wide range of applications in this wavelength range.

The lens is made from N-BK7 Schott glass, a popular material in optical systems due to its excellent optical properties and versatility. The double-convex geometry, with radii of curvature of 49.14mm and -49.14mm, ensures a high level of light concentration, making this lens ideal for imaging and other applications where light gathering is crucial.

The lens features a standard coating on both the front and back surfaces, specifically the EDM NIR-I std curve coating. This coating is designed to enhance the lens' performance within the NIR spectrum, improving transmission and reducing unwanted reflections.

The lens has a center thickness of 2.74mm and an edge thickness of 2mm, providing a robust and durable design. The lens's clear aperture is 12mm, and it has a back focal length of 47.09mm. The lens is currently in stock and available for immediate purchase, as indicated by its valid weblink status.
