Laser micro structuring of clock faces with excimer laser

IWS engineers utilize substantial equipment and facility installations and solid know-how to perform applied research projects in the field of micro and fine processing with laser beams. Targeted applications are the miniaturization of functional elements in machines, systems, vehicles, instruments and medical devices. Examples include the fabrication of 3D structures of sub-millimeter dimensions and areal structures on polymers, metals, ceramics and quartzite and biocompatible materials as well as cleaning with laser technology.


Service offers

Based on our profound technical expertise and extensive experience with industrial customers and publically funded projects, the Fraunhofer IWS offers the following capabilities:

  • Laser micro-material processing such as drilling, cutting, engraving, structuring of metal, synthetics, semi-conductors, natural substances, ceramics and thin films
  • Hybrid processing "high speed micro milling and laser structuring"
  • Laser cleaning and coating removal for technical and restoration applications of steel, granite, sandstone, copper, brass, rust, patina and graffiti
  • Analysis of works of art through terahertz radiation
  • Process diagnostics with high-speed photographic technology
 

Technologies and applications

The applications range from direct laser cutting with high precision of very diverse materials via micro mating of different combinations of materials, like ceramic membranes involving polymers as support material, through to surface modification by laser radiation.
