84-127 2 mm Dia. N-PSK53A/N-LASF9 Achromatic Doublet; EFL=3mm VIS-NIR 400-1000nm
The 84-127 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 wavelength range of 400-1000nm. This lens, with a 2mm diameter, is a multiplet type, featuring a focal length (EFL) of 3mm, making it an ideal choice for applications that require compact, high-performance optics.
The lens is composed of two types of glass, N-PSK53A and N-LASF9, both from Schott, which are renowned for their optical quality and durability. The lens features a geometry that includes an inner radius of 0mm, an outer radius of 0mm, and a thickness edge of 1.6mm. The r1 and r2 radii are 1.68mm and -1.68mm respectively, while the r3 radius is -7.39mm. The thickness at the center of the lens is 1mm, and the thickness at the center a is also 1mm.
The 84-127 lens is coated with the EDM VISNIR0SP2002000 coating on both the front and back surfaces. This coating enhances the lens's performance in the VIS-NIR spectrum, providing improved transmission and reduced reflection. The lens is currently in stock and available for immediate purchase, as indicated by its weblink status. For more information, users can visit the provided weblink.
