FT-IR Spectrometers

FT-IR Spectrometer is an instrument which acquires broadband NIR to FIR spectra.  Unlike a dispersive instrument, i.e. Grating Monochromator or Spectrograph, FT-IR Spectrometer collects all wavelengths simultaneously.  This feature is called the Multiplex or Felgett Advantage.

FT-IR Spectrometers are often simply called FT-IRs.  But for the purists, an FT-IR (Fourier Transform InfraRed) is a method of obtaining infrared spectra by first collecting an interferogram of a sample signal using an interferometer, and then performing a Fourier Transform (FT) on the interferogram to obtain the spectrum.  An FT-IR Spectrometer collects and digitizes the interferogram, performs the FT function, and displays the spectrum.
The FT-IR spectrometer has the power to handle both research and routine analysis experiments. Every facet of the FT-IR spectrometer has been engineered to facilitate sample handling, provide options for integration in the laboratory, and increase laboratory throughput.  With a huge installed base worldwide, a superior service team and the flexibility for many applications.

Choose an FT-IR over a dispersive instrument if

  • You work in the Infrared
  • You need high Spectral Resolution
  • You work with Weak Signals
  • You need to acquire your spectra Quickly and with High S/N Ratio
  • You need high Spectral Accuracy


  • This spectrometer is Insensitive to Vibration, so it can be placed almost anywhere, can be moved, and be immediately operational without any need for alignment.  Spectrometers deliver excellent sensitivity as well as x-axis reproducibility and stability
  • Plug-and-Play Operation, easy to set-up and ease of use, Brings practicality to FT-IR spectroscopy
  • OPUS/Mentor Software Interface guides the user every step of the way
  • This spectrometers offer full FT-IR sampling flexibility
  • User Exchangeable QuickSnap sampling modules allow the analysis of almost any kind of sample (e.g. solids, liquids or gases)
  • Transmission, Attenuated Total Reflection (ATR), external and diffuse reflection FT-IR sampling accessories are available
  • It combines the Highest Performance and Outstanding Flexibility with an intuitive and easy to operate interface.
  • It combines Easy Operation with Highest Instrument Performance and Affordability.
