49-950 9 mm Dia. N-BAF10/N-SF6 Achromatic Doublet; EFL=15mm VIS-NIR 400-1000nm
The 49-950 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 9mm diameter and an effective focal length (EFL) of 15mm, making it suitable for a wide range of optical applications.
The lens is constructed from two types of Schott glass, N-BAF10 and N-SF6, which are carefully selected to minimize chromatic aberration, a common issue in optical systems. The geometry of the lens is meticulously designed, with a center thickness of 4mm, edge thickness of 4.22mm, and radii of curvature of 10.49mm and -8.08mm for the first and second surfaces, respectively. The lens also features a third radius of -38.23mm, contributing to its achromatic properties.
The 49-950 is coated with Edmund Optics' VIS-NIR coating (edm visnir0sp2002000) on both the front and back surfaces. This coating is specifically designed to enhance the lens' performance in the VIS-NIR spectrum, ensuring optimal transmission and minimal reflection.
