Solutions for High Temperature Measurement

Different experimental conditions at the material surface require specific optimization of the experimental setup for successful Digital Image Correlation (DIC) measurements. Specimens which are heated exhibit black body radiation which can easily obscure the visible surface pattern. A combination of blue lighting and the correct filter blocks out the glow from the surface. LaVision offers dedicated solutions for high temperature DIC measurements in terms of lighting and optics. We are also able to give advice in terms of surface preparation suitable at very high temperatures (>1200 °C)
