In tribology the wetting behavior of liquids towards solid surfaces plays an essential role therefore an exact determination of the static or dynamic contact angle, as well as the surface and interfacial tension of liquids and solids is needed.
Keywords: Optical Contact Angle, Wetting, Surface Tension, Interfacial Tension, Surface Free Energy.
Measurements: This setup permits the precise determination of surface or interfacial tension of liquids as well as the surface free energies of solids.
