DataPhysics - OCA - Optical contact angle measuring and contour analysis systems

The optical contact angle measuring and contour analysis systems of the OCA series are high precision optical measuring devices for the measurement of interfacial parameters and phenomena.

The optical analysis of drops that hang from a dosing needle or are placed on a solid surface facilitates the determination of different surface and interfacial parameters. The contact angle that a liquid drop establishes on a solid surface characterises the solid’s wetting behaviour with said liquid.

Having measured the contact angles of multiple test liquids the surface energy of the solid can be determined and the latter can be used to calculate the work of adhesion for different liquids.

The reliable and experimentally robust measurement of the contact angle aids on the development of surface coatings, composite materials, paints and varnishes or cleaning agents. In short: the measurement of contact angle helps in all situations where solids and liquids meet and advantage is to be gained by the control of wetting and adhesion properties.
