Sample Measurement and Analysis Services
We provide sample stress measurement and analysis services. As a result of
measurement you will receive sample measurement report, supported by full
information on the traceability of our laboratory instrumentation.

In addition to standard report our engineering staff will be happy to discuss any
additional measurements such as QE mapping, roughness, diffuse reflection
whichever you may have.

Please do not hesitate to
contact us and discuss more details.
