49-373-INK 30 mm Dia. N-SSK8/N-SF10 Achromatic Doublet; EFL=75mm VIS-NIR 400-1000nm
The 49-373-INK is a high-quality achromatic doublet lens, designed and manufactured by Edmund Optics. This lens, with a diameter of 30 mm and a focal length of 75 mm, is specifically engineered for use in the visible (VIS) and near-infrared (NIR) spectrum, spanning 400-1000 nm.
The lens is constructed from two types of Schott glass, N-SSK8 and N-SF10, which are renowned for their excellent optical properties. The use of these materials ensures high-resolution images with minimal chromatic aberration. The lens features a front and back coating of EDm VIS-NIR 0SP2002000, a proprietary coating developed by Edmund Optics, which further enhances its performance in the specified wavelength range.
The lens geometry is meticulously designed, with an inner radius of 0 mm, an outer radius of 0 mm, and a thickness at the edge of 8.4 mm. The thickness at the center is also 8.4 mm, with an additional 3 mm of material at the center a position. The lens's shape is a multiplet, which is a combination of multiple individual lenses to achieve specific optical properties.
