When using laser cleaning, there are some restrictions that need to be taken into account in order to achieve optimal results. Laser cleaning technologies are most effective on dark or highly absorbent surfaces because these materials absorb laser energy well and can efficiently remove contaminants.

Transparent or reflective materials, on the other hand, pose a challenge because they do not absorb laser energy well and can instead reflect it. This can result in the cleaning process being less efficient or even impossible because the laser beams do not penetrate the material deeply enough to remove the contaminants.

Transparent materials may require special laser cleaning techniques aimed at removing surface contamination without damaging the material. For reflective materials, the use of laser beams with specific wavelengths or power adjustments may be required to achieve desired cleaning results.

It is important to consider these limitations when laser cleaning and adjust the cleaning process accordingly to achieve the best possible results. By selecting appropriate laser parameters and cleaning techniques, potential problems when cleaning transparent or reflective materials can be minimized and the efficiency of the cleaning process can be improved.
