This robust processing optics for laser powder cladding guarantees the highest flexibility for your cladding solutions.

In correspondence to your requirements we will make sure to choose the suitable type of powder nozzle and the fitting range, in which the laser spot size should vary.

ALOpowderzoom can be integrated in all our stationary laser systems. Moreover, since it is a component of our modular system configurations it can be used alternately with other optics, such as for example ALOhard for laser hardening.


  • Coating of 3D surfaces as a corrosion and wear protection
  • Repair of worn parts
  • Design modification or correction of production failures
  • Additive manufacturing of 3D parts


  • Robust stainless steel housing perfect for cladding applications
  • Variable laser track widths (from 2,5 up to 7 mm) without change of optics
  • Combinable with various powder nozzless
  • Selection of different nozzle – workpiece distances
  • System for quick replacing of cover slides

Possible powder nozzles*

Annular gap powder nozzle Multi-jet nozzle
  • with coaxial powder feeding and completely independent from any direction
  • fine powder focus
  • high deposition rate
  • operation angle up to ca. 30°
  • with coaxial powder feeding and completely independent from any direction
  • better accessibility to the part due to the high nozzle – workpiece distance (up to 25 mm)
  • operation angle up to ca. 90° and so the full 3D ability

*Integration of more types of powder nozzles is possible on request.
