Abstract
In this work we studied the contact angle of Nano liter water droplet on a Soda-Lime glass surface based on Mirau interferometric microscopy. Our analysis is based on the principle of phase shifting interferometry. This method needs a static fringe pattern. As a result we reduced the evaporation rate by a thermoelectric cooler and froze the interference pattern. By analyzing the interferometric patterns we acquired the angle of water droplet with surface. The average of this angle is 6 degree.

Abstract
Silver nanoparticles have been produced by thermal annealing method in furnace over the surface and in the ion-exchanged soda-lime glass matrix with AgNO3 / NaNO3 acid salt. Nanoparticles size is depend on their depth in the glass matrix. The annealed glass surface investigated and studied by the optical microscopy and the absorption spectroscopy. Obtained results analyzed by MATLAB are supported by experimental results. This study showed the relation of nanoparticles size and absorption spectra, where the large nanoparticles have more intense absorption.
