Die plug analysis, chloroform washing of the co-PET layer and white light interferometry were used for experimental validation of CFD results.
For final film interpretation, the co-PET thickness values were compared with both the white light interferometry thickness values and the CFD co-PET flow values.

The contours formed by white light interferometry allow Bruker testers to determine whether surface damage consists of pits, scratches, spirals, etc.
Examining devices by the nanometer, which is one-billionth of a meter, is one thing, but scientists at Bruker can drill down to the angstrom level--one ten-billionth of a meter--with white light interferometry. Thus, Bruker is able to avoid getting slowed down by the slicker polymers and more resistant materials taking longer to show wear.
