Optical and optoelectronic methods
Means
3 types of optical testing means gathering very attractive characteristics are available to fit your needs.
Features / technical details
Characteristics
These means use white light or coherent light to detect flaws or to visualize surface movements by global and free-contact methods.
Performance of means
- Afford to investigate largesized specimen
- High sensitivity
- The means may be automated to be integrated in industrial processes
Our means
- Study laboratory with optical marble and continuous or phased laser
- Stress chamber by depression
