Laboratory 2 - Analysis, Characterization, Testing.
The mission of the "Analysis, Characterization, Testing" laboratory is to characterize the properties of materials processed by laser, plasma and radiation, of devices obtained in the laboratories of the institute and provide testing and characterization services to businesses or institutions (universities / research institutes) that do not have high-performance testing capabilities.
Services offered:
- Structural and mechanical analysis center for materials subjected to thermal / mechanical stress;
- Electron microscopy center;
Morphological-structural characterization of thin films over large areas and of materials processed with laser beams, plasma and radiation;- Characterization of electrical, magnetic and optical properties of materials processed with laser, plasma and radiation;
- Mechanical characterization services for thin films used in hostile environments (high temperatures, humidity).
