KEIT’s microFTS® is a Fourier Transform Infrared (FTIR) spectrometer that is smaller, lighter and more rugged than current systems.


The microFTS® was designed for space applications where these attributes are paramount, and offers a new gold standard. The microFTS® has no moving parts, setting it apart from other FTIRs based on the Michelson interferometer. Unlike these devices, which tend to be large, heavy and vulnerable to shock and vibration, the microFTS® is compact, light-weight, and shock- and vibration-resistant. For further information on FTIR check out our technology page.


The MicroFTS® is able to bring the analytical power of FTIR spectroscopy to in-line applications without the use of remote sampling or fibre optic couplers required in current systems.
