Infrared Emission Spectrum Measurement Using FT-IR Spectrometer

The use of FTIR spectrometer for measuring emission spectrum is investigated. The additional requirements and attachments needed to fulfill this purpose are described. The results of a design effort are listed which included optical arrangement and technical parameters of the main optical parts. The paper also presents the techniques for calibration and for quantitative measurement of the emission spectra. The details are discussed in terms of the following three conditions: radiance, intensity and rapid sampling. Finally, the results of system adjustment and calibration, as well as emission spectra of some sources are given.
