49-319 9 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=60mm VIS-NIR 400-1000nm

The 49-319 is a high-quality achromatic doublet lens, sourced from the renowned optical components vendor, Edmund Optics. This lens is specifically designed for use in the visible (VIS) and near-infrared (NIR) spectrum, spanning 400-1000nm.

The lens features a 9mm diameter and an effective focal length (EFL) of 60mm, making it suitable for a wide range of applications. The achromatic design, which combines two different types of glass (N-BK7 and N-SF5), effectively corrects chromatic aberrations, ensuring sharp and clear images across the entire spectral range.

The lens geometry includes a thickness of 4.59mm at the edge, with a central thickness of 3.5mm. The first and second radii of curvature are 36.51mm and -26.33mm, respectively, while the third radius of curvature is -78.35mm. The lens is coated with a broadband anti-reflection coating, specifically the EDM VIS-NIR 0SP2002000 coating, which provides excellent transmission and reduces surface reflections.

This lens is available for purchase directly from the Edmund Optics website, and the link provided in the item data indicates that it is currently in stock. With its high-quality materials, precise geometry, and advanced coating, the 49-319 is an excellent choice for any application requiring a high-performance achromatic doublet lens in the VIS-NIR spectrum.
