In this report, several applications of near-infrared microspectroscopy are illustrated using unmodified commercial instrumentation. The principal advantage of near-infrared microspectroscopy is the ability to analyze small samples which are totally absorbing in the mid-infrared region. Near-infrared analysis is shown to yield useful structural information about several different types of samples. Examples from the fields of materials science, single crystals, forensics and biological science are illustrated, and some tentative band assignments are made.
