Multidot laser head

Spatial and dynamic laser beam shaping

VULQ1is an innovative and patentedmultidot laser headcompatible with existing IR and visible pulsed laser sources (nano-, pico- and femto-seconds).


Demo Unit (Laser Expo Piacenza 2015)

A new laser beam control

  • Instantaneous multidot marking (1D, 2D)
  • Parallel processing
  • Energy control per point
  • Working distance flexible
  • High resolution
  • Spatial and dynamic spot laser control


  • Marking on the fly
  • High-speed marking
  • Parallel processing
  • High resolution
  • Traceability
  • Anti-counterfeit


VULQ1 allows in particular a high-speed marking and decoding of identifying and / or authenticating information in different scale sizes (from a few hundred of µm² up to several mm²); on surface or in the mass of many materials (metals, polymers, ceramics, etc).

VULQ1 allows multi- and simultaneous dots marking inside transparent materials (glass, polymer, etc) whose position and distribution can be controlled spatially and dynamically.
