Patent number: 4688938Abstract: A support (56) is suitable for holding a substrate (10) horizontal, said substrate having a drop of liquid placed thereon. A source of light (74) associated with a collimator (78) forms a primary beam of parallel light which is directed perpendicularly (86) to the substrate. A receiver surface (126, 128) having a known geometry and placed in a known position relative to the substrate intercepts a secondary beam (124) produced by interaction between the primary beam and the drop and the substrate. The value of the contact angle between the drop and the substrate may be deduced from the illuminated zone on said receiver surface.Type: GrantFiled: December 4, 1985Date of Patent: August 25, 1987Assignee: Centre National de la Recherche Scientifique (C.N.R.S.)Inventors: Catherine A. Demoulin, Dominique Ausserre, Francis Rondelez
