It is a clear polymer in fact. I called the guys at Filmetrics, they were very helpful. They are going to run a free sample measurement for me. Will let you know if this works for my application.
Thanks again!
Thanks for the response.
I have come across these. But it appears that most rely on eddy currents. My substrate is non-magnetic.
I also should have mentioned that my parts are small, approx 1 mil in diameter. These handheld contact probes would not be appropriate
I am currently coating a thin polymer film on biomedical implant parts. Coatings are typically 3-4 uM thick. Having difficulty finding method of measuring coating thickness for quality control purposes. Any thoughts apreciated.
