Laser processing heads

Design and development of processing heads for laser welding, hardening and cladding technologies according to customer requirements.

The development is focused on the stability, robustness, cooling, modularity minimal installation dimensions and weight of laser processing heads for high power industrial applications.

The results of the development are then tested by real load of the LaserTherm custom production. Feedback of process ensures a high-quality and practical product ready for heavy industrial operation.

We can achieve all this thanks to our own real experiences from everyday practice.


  • Robust construction with sophisticated cooling system
  • Quick exchange of optical components
  • Long-term stability in heavy industry
  • Good performance cost/ration
  • Technical and service support directly from the manufacturer
