Optical Emission Spectroscopy
Optical emission spectroscopy involves the collection, spectral dispersion, and detection of light. Because OES from plasmas is often very strong, the light collection and detection efficiencies need

This method relies on the principle that atoms or molecules, when subjected to high energy, absorb that energy and subsequently release it as photons. Emission spectroscopy is an analytical technique used to identify and quantify elements by studying the light they emit after being energized. 1 shows a portion of the energy level diagram for sodium, which consists of a series of discrete lines at wavelengths that correspond to the difference in energy. Harri Kola's and Aulis Hakkarainen's presentations in POHTO (2012) have been used as source materials.
