The ellipsometer uses a nondestructive (noncontact) optical method to determine film thickness and optical properties. It measures thin films and almost any material deposited on a substrate. This might include thin metal films, oxides, organic coatings, or biological molecule layers such as DNA. While ellipsometry was originally a technique for macroanalysis, this device combines original technology with polarization contrast microscopy to give it the capacity to perform microanalysis.
Equipment for measuring various aspects of your substrates both during and after your fabrication.
