Prism

Prism residual stress is a measurement technology that dramatically improves the ability to make quick, accurate residual stress measurements. The technology utilizes stress-relaxation technique, where a small hole is drilled into the material thus relaxing the stress along the hole boundaries. The resulting surface distortion can then be measured precisely using electronic speckle pattern interferometry system (ESPI).

The system software is fully integrated to be able to provide in automated data storage and make analysis, with as a result a complete stress profile. This affordable and user friendly technology is applicable to every application and can be constantly optimized.
