The ViSWIR Hyper APO series objectives provide high resolution in the wavelength range between 400 and 1,700 nm, with full correction of focus shift. By using very low dispersion and low partial dispersion glass, focus shift is minimized within a few microns over a very wide wavelength range. This allows spectral imaging with a single sensor camera by simply synchronizing the illumination. Instead of the usual 1-inch format, this ViSWIR Hyper-APO lens has a 2/3-inch format. In addition, there is no need to adjust the focus for different wavelengths.
