The Optical Research Dilatometer L74 was developed to meet the demanding applications of the glass, ceramics, metal and energy industry. A high resolution CCD camera enables a visual real time analysis of the sample expansion, either as single frame or as video sequences. The big advantage of this method is that the sample is not burdened with any force. For soft samples or samples that melt during the measurement, this leads to a result, which is not distorted by the contact pressure.
