Laser-Induced Breakdown Spectroscopy (LIBS) is a method of analytical chemistry that provides a qualitative and quantitative analysis of a sample. The ablation process of a sample is fast and dynamic and the change of plasma in time and space is a question of a few microseconds. An examination that provides a good time and space resolution is necessary to understand better the physical processes. For this reason, the goal of this work is to design a basic optomechanic construction for this type of experiment. Optomechanic modul consist of objective that collects the emited radiation and focus it on the CMOS detector. For each experiment multiple images of the plasma are collected for better accuracy. Firstly basic comparison between the spectroscopic and imaging data is observed. For this experiment size of the plasma is compared with emited radiation colleted with spectometer. Also, the time development of plasma will be observed under different experimental conditions. The goal of this work, in general, is to prove that the morphology of plasma is as it is described in available related literature.
