Infrared emission spectrum
Webb1 jan. 2012 · An experimental setup is developed to analyze infrared emission of CO 2 plasmas at atmospheric pressure and temperatures up to 5000 K. A microwave discharge is used to produce the hot gas mixture and emission is recorded by a Fourier transform spectrometer with a spectral resolution between 0.01 and 0.1 cm −1.The plasma is … WebbDifferent wavelengths of light reveal different natural phenomena, and the infrared has an important story to tell. One of the advantages of observing in the near-infrared is that dust is transparent to it. This is why an optical telescope would be unable to see a star enshrouded in dust, whereas one working in the near-infrared would be able ...
