Functionalization and structuring of surfaces


Laseroberflächenfunktionalisierung zur       Einstellung der Wasserbenetzbarkeit

The LZH offers consulting, feasibility studies and process development for the functionalization and structuring of surfaces. Here, ultrashort pulse lasers offer manifold possibilities to modify surface properties in a well-targeted manner to match the requirements of diverse applications. One example is the generation of hydrophobic surfraces.

Laser polishing of glass surfaces and edges


Laserverrundete Glaskante

With laser-based melting, edges can be rounded off and surfaces can be polished locally. This process is non-tactile, can be used for different geometries, and does not require polishing agents.

Marking and writing on glass


Lasermarkiertes Schachbrett auf Glasbasis

With the laser, glass can be flexibly marked and structured. The transparency of the laser-marked area can be accurately pre-defined. Even pre-stressed glasses can be precisely marked with the laser.
