Details
The thin film analyzer works based on the intensity measurement of reflecting and transmitting light through the sample. Hence, thickness of only transparent coatings can be measured, though the substrates can be of transparent or non-transparent nature. There are possibilities of using a contact or a non-contact probe depending upon the nature of film and the substrate.
