Stamp marking

Stamp marking is the ability to mark 2D patterns, typically 2D barcodes but also pictures or characters, with one single laser pulse.

Stamp marking unleashes dramatic productivity potential for 2D barcode marking, combined with straightforward implementation. For lot marking, the 2D barcode marking rate is equal to the laser repetition rate, typically reaching several 10’s or 100’s of marking per second!

The pattern size can be down to 100 microns while conserving a perfect readability, even on moving parts, because all the dots are marked simultaneously.
