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.

Laser marking inside transparent materials features:
  • Colourful structures in glass and sapphire
  • Surface not affected
  • Very small or no cracks near markings
  • Low influence on strength of the substrate
  • No heat affected zones
  • High positioning accuracy (3D marking available)
