Non-destructive measurement of coating thickness on plastics

We measure the thickness of:

  • abrasion- and scratch-resistant coatings
  • chemically resistant coatings
  • antistatic coatings
  • coloring layers
  • reflective coatings

A new dimension in production control

When wet food is packaged, full-surface inspection of the sealed seam with high geometric resolution and high speed is of great interest. This task can only be solved with light.


The Movie shows a micro hole with a diameter of about 50 µm in a food packaging with integrated Alufoil. You can see the puncture with a needle from the outside. The micro hole tapers inwards and reaches a minimum diameter of about 10 µm.


Failure in the sealed seam; Size approx. 100 µm


Delaminatin of two layers; the separation layer is only a few µm thick and about 100 µm long.
