49-321 12.5 mm Dia. N-BAF10/N-SF5 Achromatic Doublet; EFL=14mm VIS-NIR 400-1000nm
The 49-321 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 12.5mm diameter and an effective focal length (EFL) of 14mm, making it suitable for a wide range of optical applications.
The lens is composed of two elements: N-BAF10 and N-SF5, both from Schott. These materials are known for their excellent optical properties, contributing to the lens's high performance. The lens is coated with edm visnir0sp2002000 on both the front and back surfaces, further enhancing its capabilities in the VIS-NIR spectrum.
The lens geometry is intricately designed, with a center thickness of 6.23mm and an edge thickness of 5.34mm. The radii of the three surfaces are r1=10.6, r2=-7.72, and r3=-56.54. The lens also features an inner radius of 0 and an outer radius of 0.
