49-794-INK 25.4 mm Dia. N-SSK8/N-SF56 Achromatic Doublet; EFL=76.2mm VIS-NIR 400-1000nm
The 49-794-INK is a high-quality achromatic doublet lens, boasting a 25.4 mm diameter and an effective focal length (EFL) of 76.2mm. This lens is designed for use in the visible (VIS) and near-infrared (NIR) spectrum, specifically catering to the wavelength range of 400-1000nm.
The lens is composed of two elements, made from N-SSK8 and N-SF56 Schott glass, which are renowned for their excellent optical properties. The first element has a radius of curvature (R1) of 50.85mm, while the second element has an R1 of -40.06mm and an R2 of -148.78mm. The center thickness of the lens is 7mm, with a 3mm thickness at the edge.
The 49-794-INK lens is coated with Edmund Optics' VIS-NIR-0SP2002000 coating on both the front and back surfaces, enhancing its performance in the specified wavelength range. This lens is a multiplet, meaning it is composed of multiple elements, and it has a circular base shape.
The lens is currently in stock and available for purchase from Edmund Optics. For more information, including pricing and availability, please refer to the provided weblink.
