Abstract

A novel instrument for the measurement of polymer film coatings is reported and evaluated. The device uses a measurement technique based upon conventional beam profile reflectometry but which has been adapted to work on highly curved surfaces such as those found on medical implants. The instrument was used to measure polymer film thickness on a range of test artifacts with varying film thickness and surface curvature. The results obtained were then compared with those made at the National Physical Laboratory using alternative measurement techniques to assess the accuracy of the measurement system.
