83-417-INK 12.7 mm Dia. N-BK7/N-SF5 Achromatic Doublet; EFL=125mm VIS-NIR 400-1000nm
The 83-417-INK is a high-quality achromatic doublet lens, designed and manufactured by Edmund Optics. This lens, with a diameter of 12.7 mm, is specifically engineered for use in the visible (VIS) and near-infrared (NIR) spectrum, spanning from 400 to 1000 nanometers.
The lens features a focal length (EFL) of 125 mm, making it suitable for a wide range of optical applications. The achromatic design, which combines two different types of glass (N-BK7 and N-SF5), effectively reduces chromatic aberration, ensuring sharp and clear images across the entire spectral range.
The lens geometry includes a thickness of 6.11 mm at the edge, with the inner and outer radii being 0. The center thickness is 4.5 mm, with an additional 2 mm thickness at the back. The lens's base shape is circular, and it is coated with EDMM VISNIR0SP2002000 on both the front and back surfaces, enhancing its transmission capabilities in the VIS-NIR range.
According to the vendor's information, this item is currently in stock, and the web link provided leads to its product page on the Edmund Optics website. This lens is a multiplet, meaning it consists of multiple elements, making it a versatile and high-performing optical component.
