ABSTRACT:
A method and apparatus for optically making physical measurements of materials which deform upon application of heat thereto. The device comprises a source of light, an at least partly transparent chamber having a heating source which can be programmed to operate as a function of time, and with a porous support designed to support a deformable material within the chamber. A photo-electric receiver 5 and an optical lens 7 are also provided for imaging of the material during deformation on the photo-electric receiver. In order to perform the imaging, the source of light, the porous support, the photo-electric receiver and the optical lens 7 are optically aligned. In a specific application, the apparatus can be used to determine the wetting power of pitches.
