Terahertz spectrometers make use of the remarkable properties of THz light and allow for identification, analysis and imaging. The variety of applications ranges from pharmaceutical drug formulation over medical diagnostics to the detection of contraband

By applying different software analysis packages, the same base technologies can be brought to bear to a wide range of applications; including drug discovery and formulation; medical and dental diagnostics; security screening, explosives detection and contraband detection. In cases of the above mentioned applications where no phase information is needed, FTIR technology  can serve as an economically attractive  alternative solution and the spectral information down to
5 cm^-1 (=0.15 THz) can be collected e.g. with Bruker VERTEX 80v  FTIR vacuum spectrometers
