One of the areas where LIBS is used is the creation of chemical maps of studied samples. Measurements made by this method are significantly influenced by the lens to sample distance. At the wedgewise samples this distance is changing during the measurement which decreases the quality of the chemical maps created. In this bachelor’s thesis a method of wedgewise correction is proposed and experimentally verified. A part of this thesis is a description of basics of laser spectroscopy and a summary of some variables influencing the LIBS experiment. The main part of the thesis is a proposal of wedgewise correction algorithm. At the end the results of measurement with the use of the proposed method are presented.
