Contactless Video Extensometers

Applied Standard


  • Deformation measurement of samples during material testing with use of the Video extensometer MercuryRT allows applying multiple virtual probes (Movement Sensors)on markers and advanced image featuresto be tracked, including the natural pattern of the sample surfaces. The common resolution of standard system is within 500 nm and 5 m. 
  • The system fulfils class 0.5 or B-1 of classification according to ISO 9513 and ASTM E83. In certain camera use case, the system resolution reaches the level of 100 nm - 500 nm and system fulfils the class 0.2. The strain resolution can reach 10 microstrains.
