In the Materials Industry, dimensional measurement can yield much knowledge of the properties of materials including wear characteristics, compressibility, and coefficient of thermal expansion.  Customers such as ASML, Corning, Alcoa, LenovoEMC, Optimax, IBM, 3M Corporation, and NASA use Pratt & Whitney laser-based interferometers in measuring foil, film, and mesh thickness as well as other substrates ranging from fractions of a nanometer to several micrometers in thickness.
