49-950-INK 9 mm Dia. N-BAF10/N-SF6 Achromatic Doublet; EFL=15mm VIS-NIR 400-1000nm
The 49-950-INK 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 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 lens geometry is meticulously designed, with a central thickness of 4mm and edge thickness of 4.22mm. The lens surfaces are inscribed with radii of 10.49mm and -8.08mm on the first and second surfaces, respectively, and -38.23mm on the third surface. The lens also features a minor thickness of 1.5mm at the center.
The lens is coated with Edmund Optics' proprietary VIS-NIR coating (edm visnir0sp2002000) on both the front and back surfaces, enhancing its transmission capabilities in the VIS-NIR spectrum. This lens is currently in stock and available for immediate shipping, as indicated by its valid weblink status.
