Optical Tensiometers

Optical tensiometry is a technique used to measure the surface tension of liquids by analyzing the shape of their interfaces. It utilizes optical imaging systems, such as cameras, to capture images of the liquid interface. By quantifying the curvature or deformation of the interface, optical tensiometry can accurately determine the surface tension of the liquid. This method is widely used in scientific research and industrial applications to study the properties of liquids, emulsions, and coatings.
