FTIR Spectrometer

FTIR Spectrometer

An FTIR Spectrometer is a spectrometer that collects and digitizes the interferogram, performs the FT function, and displays the IR portion of the spectrum.

The FTIR is based on a Michelson Interferometer, which consists of more than a beam splitter and two mirrors. It produces interference between double beams of light waves propagated through 2 separate optical path lengths and just the useful interference only occurs between light waves of the same frequency and constant phase relation.cite book |author=Lau, William W. |authorlink= |editor= |others= |title=Infrared Characterization for Microelectronics |edition= |language= |publisher=World Scientific Publishing Company |location= |year=1999 |origyear= |pages= p4|quote= |isbn=981-02-2352-8 |oclc= |doi= |url= http://books.google.com/books?id=rotNlJDFJWsC&pg=PA4&vq=A+more+modern+infrared&dq='FTIR+Spectrometer'&source=gbs_search_s&sig=ACfU3U3yTgqlTEnctrmZODvuixTcdLSBzQ|accessdate=]
