thin polymer film
(OP)
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.

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

Can you give us better description of your part.
By the way when we were working on implants Al was a definite no,no.
If your film is clear you could talk to Filmetrics.

You could use this laser micrometer from Keyence to measure you coating.
