- Sample size
- Sample manufacturer
- Material of the sample and structure
- Layout
- Mark for identifying the orientation of the sample
- Sample status (e.g. contamination)
- Sample mounting
- Measurement positions
- Targeted measurement uncertainty
We suggest that our customer provides detailed drawing(s) to illustrate clearly the Layout and measurement positions of the sample.
