I want to know about the optical method to measure the thickness of the sample (thin film, polymer, and crystal)? and what is the parameter that we need to measure it?
There are many methods to measure the thickness of thin films but I thought that interferometer measurement.
In Iraq, the best equipment was found in Baghdad Univ. college of sciences, dept. of physics (this for thin film thickness.) . for polymer matrix film I think that the equipment found in the center of energy and renewable energy is the accurate....this is our bits of knowledge
