49-791-INK 25.4 mm Dia. N-BAF10/N-SF6 Achromatic Doublet; EFL=38.1mm VIS-NIR 400-1000nm

The 49-791-INK is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 25.4 mm, is designed for use in the visible (VIS) and near-infrared (NIR) spectrum, spanning 400-1000nm. The lens is specifically designed for use in a variety of applications, including but not limited to, imaging, beam shaping, and focusing.

The lens features a focal length of 38.1 mm, providing a balance between field of view and focus. 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 lenses. The geometry of the lens is meticulously designed, with edge and center thicknesses of 9.44 mm and 10.5 mm respectively, to ensure optimal performance.

The lens is coated with Edmund Optics' proprietary VIS-NIR coating (edm visnir0sp2002000), which is applied to both the front and back surfaces. This coating enhances the lens's transmission capabilities, reduces surface reflections, and increases overall durability.
