49-303 6.25 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=10mm VIS-NIR 400-1000nm
The 49-303 is a high-quality achromatic doublet lens, designed and manufactured by Edmund Optics. This lens is characterized by its 6.25 mm diameter and a focal length of 10mm, making it suitable for a wide range of applications in the visible and near-infrared spectrum (400-1000nm).
The lens is composed of two elements: N-BAF10 and N-SF10, both from Schott. These materials are known for their excellent optical properties, making them ideal for use in high-precision optical systems. The lens features a sophisticated geometry, with radii of curvature of 6.98mm, -4.35mm, and -41.01mm, and a center thickness of 3.06mm. The edge thickness is 3.23mm.
The lens is coated with a broadband anti-reflection coating, specifically the EDM VIS-NIR 0SP2002000 coating, on both the front and back surfaces. This coating is designed to minimize surface reflections and increase transmission in the visible and near-infrared regions, enhancing the overall performance of the lens.
The 49-303 is currently in stock and available for purchase through the Edmund Optics website. Its catalog number is 49-303.
