optical emission spectroscopy 

Initialism: OES
https://doi.org/10.1351/goldbook.08513
Measurement principle of atomic emission spectroscopy in which the emitted electromagnetic radiation is in the range of frequencies from the infrared, through visible, to the ultra-violet region.
Note:
OES is used as the detector in inductively-coupled plasma optical emission spectroscopy, and glow-discharge optical emission spectroscopy.
