49-459 6mm Dia. x 12mm FL; NIR I Coated; Double-Convex Lens NIR I 600-1050nm

The 49-459 is a high-quality double-convex lens, boasting a 6mm diameter and a 12mm focal length. 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 spectrum, specifically between 600nm and 1050nm, making it ideal for a wide range of applications in this wavelength range.

The lens is constructed from Schott's n-BK7 glass, a material well-known for its excellent optical properties, including a high Abbe number and low dispersion. This makes the lens suitable for use in high-precision optical systems where chromatic aberration needs to be minimized.

The lens features a standard coating on both the front and back surfaces. This coating, identified as 'edm nir-i std curve', is specifically designed for use in the near-infrared spectrum. It enhances the lens's performance by reducing surface reflections and improving transmission within the specified wavelength range.

The geometric specifications of the lens include a 6mm diameter, a 1.64mm edge thickness, and a 2.4mm center thickness. The front and back radii of curvature are 11.98mm and -11.98mm, respectively, resulting in a back focal length of 11.18mm. The effective focal length of the lens is 12mm.
