I would like to introduce to you the LASAW-NC instrument. The LASAW-NC 
uses laser generated surface acoustic waves to measure physical 
properties of density, elasticity, and Poisson’s ratio of thin film 
materials. The LASAW technique is especially effective for soft thin 
film materials such as polymers and organo-silicates. 

The LASAW-NC can effectively analyze these properties for most thin 
film materials down to around 1000 angstroms in thickness, a 
substantial improvement over the 3000 angstroms limitation of nano-
