49-784 12.7 mm Dia. N-BAF10/N-SF57 Achromatic Doublet; EFL=15mm VIS-NIR 400-1000nm

The 49-784 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 12.7mm diameter and an effective focal length (EFL) of 15mm, making it suitable for a wide range of optical applications.

The lens is composed of two elements: N-BAF10 and N-SF57, both from Schott's extensive material library. These materials are carefully selected for their optical properties, contributing to the lens's overall performance. The lens is coated with Edmund Optics' VIS-NIR coating (edm visnir0sp2002000), which is applied to both the front and back surfaces, enhancing its transmission capabilities across the specified spectrum.

The lens geometry is meticulously designed, with a center thickness of 6.5mm and edge thickness of 5.72mm. The lens features three radii of curvature: r1 at 10.59mm, r2 at -8.26mm, and r3 at -30.7mm. The lens's base shape is circular, and it is classified as a multiplet due to its multiple elements.
