49-317 9 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=40mm VIS-NIR 400-1000nm
The 49-317 is a high-quality achromatic doublet lens, sourced from the renowned optical components 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 40mm, making it suitable for a wide range of applications that require compact, high-performance optics. The lens is constructed from two types of glass, N-BK7 and N-SF5, both from Schott, ensuring excellent optical performance.
The geometry of the lens is carefully crafted, with a center thickness of 3.73mm and edge thickness of 4.45mm. The lens features three radii of curvature: r1 at 24.77mm, r2 at -18.01mm, and r3 at -51.17mm. These parameters contribute to the lens's high-quality imaging capabilities.
The lens is coated with Edmund Optics' VIS-NIR coating (edm visnir0sp2002000) on both the front and back surfaces, enhancing its transmission capabilities across the VIS-NIR spectrum. This coating ensures high transmission, low reflectance, and excellent environmental stability.
