Laser Micro Marking

Laser marking on the surface of various materials allows us to create logos, images, text, bar codes, security and identification marks, or any other plane objects on the surface of many materials with micrometer precision.



  • High contrast
  • High durability
  • Colorful structures available
  • Very small or no cracks near markings
  • No heat-affected zones
  • High positioning accuracy

Laser marking inside transparent materials

The main advantage of laser marking inside transparent materials is that information (serial number, logos, images, bar codes, security, and identification 2D/3D marks) can be written directly inside the object by making refractive index irregularities without damaging the surface.

  • Colorful structures in glass and sapphire
  • Surface not affected
  • Very small or no cracks near markings
  • Low influence on the strength of the substrate
  • No heat-affected zones
  • High positioning accuracy (3D marking available)
