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).
Features
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
- …
Applications
- Marking on the fly
- High-speed marking
- Parallel processing
- High resolution
- Traceability
- Anti-counterfeit
Examples:
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.
