49-787-INK 12.7 mm Dia. N-SSK8/N-SF56 Achromatic Doublet; EFL=31.75mm VIS-NIR 400-1000nm

The 49-787-INK is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 12.7 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 multiplet configurations, making it an ideal choice for complex optical systems.

The lens features a focal length of 31.75mm, providing a balanced compromise between field of view and focus. The geometry of the lens is carefully crafted, with an edge thickness of 4.45mm and a center thickness of 4mm. The lens also features a central thickness 'a' of 1.75mm, providing additional design flexibility. The inner and outer radii of the lens are 0, indicating a circular shape that can be beneficial in certain optical configurations.

The lens is composed of two materials, N-SSK8 and N-SF56, both from Schott. These materials are chosen for their excellent optical properties in the VIS-NIR spectrum. The lens is coated with Edmund Optics' proprietary VIS-NIR coating (edm visnir0sp2002000) on both the front and back surfaces, enhancing its performance in the specified spectrum.

The lens is currently in stock and available for immediate purchase. For more information, including pricing and detailed specifications, please refer to the provided weblink.
