49-460 6mm Dia. x 18mm FL; NIR I Coated; Double-Convex Lens NIR I 600-1050nm

The 49-460 is a high-quality double-convex lens, boasting a 6mm diameter and a focal length of 18mm. 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 600nm and 1050nm, making it ideal for a wide range of applications within this spectrum.

The lens is constructed from N-BK7 Schott glass, a material well-known for its excellent optical properties, including high homogeneity and low auto-fluorescence. This ensures the lens delivers clear, high-resolution images, free from distortions or aberrations.

The 49-460 features a standard curvature coating on both the front and back surfaces, specifically the EDM NIR-I std curve. This coating is designed to enhance the lens' performance within the NIR spectrum, reducing reflections and increasing transmission. The coating also provides protection against environmental factors, such as dust, moisture, and scratches, ensuring the lens maintains its performance over time.

The lens' geometry is meticulously designed, with a central thickness of 2.2mm and an edge thickness of 1.7mm. The front and back radii of curvature are 18.22mm and -18.22mm, respectively, contributing to the lens' high performance. The back focal length is 17.26mm, and the lens has no inner or outer radius, indicating a uniform thickness.
