49-314 9 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=18mm VIS-NIR 400-1000nm
The 49-314 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 features a 9mm diameter and an effective focal length (EFL) of 18mm, making it suitable for a wide range of optical applications.
The lens is constructed from two types of glass, N-BAF10 and N-SF10, both from Schott. These materials are chosen for their excellent optical properties, contributing to the lens's high performance. The lens is coated with a broadband anti-reflection coating, specifically the EDM VIS-NIR 0SP2002000 coating, which further enhances its performance by reducing surface reflections and increasing transmission.
The lens geometry is also noteworthy. It has a thickness of 4.49mm at the edge, with a central thickness of 4.32mm. The lens features two radii of curvature, R1 and R2, measuring 12.37mm and -7.38mm respectively. There is also a third radius, R3, which measures -73.86mm, contributing to the lens's complex optical design.
