Abstract
A device for analyzing the material composition of a sample via plasma spectrum analysis includes a laser assembly configured to emit a beam for plasma spectrum analysis and an optical assembly configured to direct the beam towards a target for plasma spectrum analysis of the target. The optical assembly is configured to collect a plasma emitted light emitted from a plasma and provide the plasma emitted light to a dispersion module. The dispersion module includes a first and second diffraction gratings. The first diffraction grating and second diffraction grating are positioned within the dispersion module such that light received from the optical assembly contacts the first diffraction grating at least two times before being directed out of the dispersion module.
