Glass and Sapphire Laser Marking

We provide laser micro marking services on surfaces and inside transparent materials.

Laser marking on the surfaces 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.

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.

  • Colourful structures in glass and sapphire
  • Surface not affected (in case of inside marking)
  • 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)
