Optical contact angle measurement is a versatile technique for analyzing surface and interfacial properties. It can be used to measure the contact angle of a liquid drop on a solid surface, which can be used to determine the surface energy of the solid and the work of adhesion for different liquids. This static and dynamic contact angle measurement technique, also known as the sessile drop method, is used to analyze the wettability of solids. Optical contact angle measuring instruments/devices are also known as drop shape analyzers or contact angle goniometers.

Optical contact angle measurement can be used in a wide range of applications, including:
  • Development and quality control of surface coatings: Contact angle measurement can be used to determine the wettability of a surface, which can be used to optimize the performance of surface coatings.
  • Surface finishing: Contact angle measurement can be used to characterize the surface roughness of a material, which can be used to improve the performance of surface finishing processes.
  • Paints and varnishes: Contact angle measurement can be used to determine the adhesion of paints and varnishes to a surface, which can be used to improve the durability of these coatings.
  • Cleaning agents: Contact angle measurement can be used to determine the effectiveness of cleaning agents, which can be used to improve the cleanliness of surfaces.
  • Optical measurement of surface tension and interfacial tension of a wide range of liquids using the pendant drop method.
