Ultrafine Marking
Ultrafine marking applications are used in
manufacturing for identification, part numbering
and serialization ranging from alphanumeric
to bar codes and data matrix /QR Codes.
Considerations when establishing a laser
marking process are laser wavelength
and pulse characteristics for appropriate
contrast in the application, and
whether the feature is machined
into the surface or a more
secure sub-surface
patterning is used.
