Glow discharge imaging spectroscopy with a novel acousto-optical imaging spectrometer

Author affiliations

Abstract

A novel Acousto-Optical imaging Spectrometer (AOS) was developed with unique features that make it attractive for different applications and fundamental investigations in atomic spectroscopy. Spatial resolution of the AOS is approximately 125 μm. Spectral resolution varies from 0.05 nm to 0.3 nm (full width at half maximum, FWHM) between 250 nm and 800 nm, respectively. Time resolution is 5 ns. Thus, the constructed AOS provides enough spatial, spectral and time resolution for applications in glow discharge imaging spectroscopy. Fast switching between different spectral lines within 200 μs can be used e.g. to investigate the evolution of different spectral lines quasi-simultaneously.
