From micro to macro: NIR sensors and imaging spectroscopy - a perfect match

Image capture in the near-infrared spectrum (NIR) at wavelengths up to 2.5 um is gaining ever greater economic significance. This is especially true in regard to imaging spectroscopy: hyperspectral microscopes, for example, can accelerate the design process of new kinds of LED structures; multispectral online inspection of recyclable materials ensures unmixed waste separation; and finally, in the arts, multispectral reflectography serves as a tool revealing the secrets of old masters and their works.
