63-628 5mm Dia. x 15mm FL; NIR I Coated; Double-Convex Lens NIR I 600-1050nm

The 63-628 is a high-quality double-convex lens, designed and manufactured by Edmund Optics. This lens, with a diameter of 5mm and a focal length of 15mm, is specifically coated for the Near-Infrared (NIR) spectrum, making it ideal for applications within the 600-1050nm range.

The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The double-convex shape, characterized by two outwardly curved surfaces, provides a wide range of focusing capabilities, making it suitable for various optical systems.

The front and back surfaces of the lens are coated with Edmund Optics' standard NIR-I coating, which is designed to enhance transmission in the NIR spectrum. This coating helps to reduce reflection and increase the overall efficiency of the lens.

The lens has a central thickness of 2mm and an edge thickness of 1.58mm, providing a robust structure while maintaining a compact form factor. The inner and outer radii are 0mm, indicating a symmetrical curvature. The back focal length (BFL) is 14.33mm, which is a critical factor in determining the position of the lens within an optical system.
