Accurate and reliable characterization of solids and liquids is essential in medical applications as well as in pharmaceutical and industrial production sites. Vibrational microspectroscopy techniques such as quantum cascade laser based (QCL-IR), Fourier Transform IR-microscopes or near field scanning imagers have been established. Here we demonstrate how modern IR- spectroscopy and imaging from micro to nanoscale can provide a deep insight on the chemical composition. Here we use a dental application as an example for highlighting the potential of combining different techniques. The different results achieved by using complementary systems are presented.
