This processing optics for laser hardening has a fixed laser track width.
It is compact, light and at the same time robust in the process.

ALOhard can be integrated in all our 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 ALOpowder for laser cladding by powder.


  • Laser hardening with a fixed track width of simple serial parts used in the field of mechanical engineering as well as of tools and molds


  • Low weight for robots with a lower load capacity
  • Compact structural form and less interference contours
  • Rectangular focus with homogeneous intensity distribution of laser beam
  • System for quick replacing of cover slides


  • Fixed spot size (different diameters are available)
  • (Optional) Connection for camera, pyrometer and temperature measuring system
  • Water cooling
  • Quick-change cover slide
  • Protective cover
