49-324 12.5 mm Dia. N-SSK8/N-SF10 Achromatic Doublet; EFL=30mm VIS-NIR 400-1000nm
The 49-324 is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens is specifically designed for use in the visible (VIS) and near-infrared (NIR) spectrum, spanning 400-1000nm. The lens boasts a 12.5mm diameter and an effective focal length (EFL) of 30mm, making it suitable for a wide range of optical applications.
The lens is composed of two elements, made from N-SSK8 and N-SF10 Schott glass. These materials are chosen for their excellent optical properties, particularly their low dispersion, which helps to minimize chromatic aberration. The lens features a complex geometry, with radii of curvature of r1=15.97mm, r2=-15mm, and r3=-528.23mm. The edge thickness is 4.39mm, while the center thickness is 4.5mm, with an additional 1.2mm at the center a.
The 49-324 lens is coated with a broadband anti-reflection coating, specifically the EDM VIS-NIR 0SP2002000 coating. This coating is designed to reduce surface reflections across the entire VIS-NIR spectrum, enhancing the lens's light transmission capabilities. The lens is currently in stock and available for immediate purchase through the Edmund Optics website.
