SPS-300 FTIR Terahertz Spectrometer

The SPS-300 from Sciencetech is the most powerful terahertz Fourier transform infrared (FTIR) available in the mid and far infrared range.

With a wide variety of optional upgrades and components to suit any research application, the SPS-300 has been successfully used in a wide range of fields by distinguished customers including the European Space Agency, the Max Planck Institute, the Argonne National Labs, The Canadian National Research Council, the Brookhaven National Lab, L'Institute d'Astrophysique Spatiale, Lawrence Berkeley National Lab, and many universities the world over.

The instrument is designed for research applications and therefore features special hardware and software designed to allow the use of samples under many different research environments such as high vacuum and magnetic fields and high and low temperatures and pressures. The SPS-300 conducts sensitive and fast "Rapid Scans" with the mirror moving continuously as the detector collects data. Researchers are also supported with custom made coupling devices and sophisticated sample chambers to meet specific needs.
