Imaging spectrographs preserve spatial details imaged onto a spectrograph slit throughout the whole of their optical system. This grants access to spatially resolved spectral information, in our case about both plasma induced processes and, concurrently, to properties of the plasma. We have implemented a fast direct vision spectrograph for imaging in near real time, which allows access to process parameters in near real time as well. This is of marked interest for studying processes near the plasma liquid interface in the plasma induced formation of silver nanoparticles (AgNP). Taking spatially resolved absorption spectra of the AgNP simultaneously with the emission spectra of the plasma permits local process parameters to be observed in real time and investigated with a view to adjusting conditions of the reaction accordingly.
