WHAT WE OFFER

Precision Surface Cleanliness with OSEE Technology

Surface Cleanliness Monitoring instruments utilize the Optically Stimulated Electron Emission (OSEE) principle to deliver quantitative, non-destructive analysis of surface contamination. With sensitivity down to the angstrom level, these instruments detect thin films, residues, and coatings, making them ideal for critical surface preparation and quality control.
