Glasses and Optical Components

Because of their optical, mechanical and thermal properties, glasses are used in a variety of applications. By varying the chemical composition (e.g., doping with impurity elements) or by deposition of chemically or structurally different layers, the properties of the glass can be tailored to a specific end application. Analysis of the near-surface composition and/or the topography is of interest in product development and failure analysis. Surface analysis methods are used to address:
  • Chemical composition of the glass
  • Determination of layer structure
  • Adhesion behavior
  • Efficiency of cleaning steps
  • Glass corrosion
  • Transportion residues
  • Staining
  • Debris formation due to use
  • Buried defects near the surface
  • ...
