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.
Keywords: Contact Angle, Measurement, Mirau Interferometer Microscope, Phase Shift, Thermoelectric Cooler.
