Contact angle measurement allows users to characterize the hydrophobicity or hydrophilicity of a surface. The technique can be used to calculate the surface free energy of a sample. Contact angle measurements are often used to help characterize samples after surface treatments such as O2 plasma treatment. It is useful in adhesion studies. A surface with a higher surface free energy will generally have better adhesion properties.

This is a home built system that captures a digital image of the droplet and then uses an ImageJ plug-in to analyze the contact angle.
