OES Code

An Introduction

Optical emission spectrum (OES) is a collected data from spectral dispersion which is gathered from light emission of objects. Here, the cold plasma emits light which can be detected using CCD camera and series of lenses (usually fused-silica).

This analysis can be used to detect elements by applying an electric discharge to vaporize chemicals which finally generates plasma emission (e.g. ICP-OES). The electron transition between energy levels emits specific photon (E=hv=hf). The collected data is related to specific elements (atoms + ions), so we can find the unknown peaks using NIST database.

Code

I tried to write a code to locate peaks of cold plasma for accurate analysis of optical emission spectra (OES) of plasma.
sample data: Argon plasma
reference data: NIST Argon peaks-observed wavelength in air

Isn’t it cool?
