Optical Emission Spectroscopy
Optical Emission Spectroscopy (OES) is a technique used to analyze the light emitted by plasma, which is an ionized gas found in various environments, including stars and industrial processes. When the plasma's atoms and molecules become excited, they release light at specific wavelengths. By examining this light, scientists can identify the elements present and determine their concentrations. This method is invaluable in plasma diagnostics, helping researchers monitor and control plasma behavior in applications such as fusion energy, semiconductor manufacturing, and environmental studies. OES provides real-time insights into the chemical composition and physical conditions of the plasma.
