Our benchtop THz spectrometer is an easy to use device, designed for laboratories where, e.g., material characterization shall be performed in the THz region. The spectrometer comes with an internal sample compartment, which can be purged with nitrogen, or with external fiber-coupled antennas. Both setups can be used to conduct transmission and reflection measurements with a collimated or focused THz beam. The spectrometer is controlled via USB using a laptop running our T3DS software package.
