84-129 2 mm Dia. N-PSK53A/N-LASF9 Achromatic Doublet; EFL=6mm VIS-NIR 400-1000nm
The 84-129 is a high-quality achromatic doublet lens from Edmund Optics, designed for use in the visible (VIS) and near-infrared (NIR) spectrum, specifically catering to the 400-1000nm range. This lens, with a 2mm diameter, is a multiplet type, featuring a base shape that is circular.
The lens's geometry is meticulously designed, with an effective focal length (EFL) of 6mm, providing a compact and efficient optical solution. The inner radius is 0, while the outer radius is also 0, indicating a symmetrical design. The lens's edge thickness is 1.82mm, and the center thickness is 1mm, ensuring robustness and precision. The radii of curvature for the first and second surfaces are r1=3.5mm and r2=-3.5mm, respectively, while the third surface has a radius of curvature of r3=-14.26mm.
The lens is composed of two types of Schott glass, N-PSK53A and N-LASF9, each selected for their specific optical properties, contributing to the lens's overall performance. The lens is coated with EDMM VISNIR0SP2002000 on both the front and back surfaces, enhancing its transmission capabilities across the VIS-NIR spectrum.
This lens is currently in stock and available for purchase through the Edmund Optics website, as indicated by its valid weblink status. The catalog number for this item is 84-129, making it easy to locate and reference in future searches or discussions.
