Nanometer Calibration Standards

Q: What is the difference between a traceable calibration STANDARD and an ordinary calibration REFERENCE specimen?

A: The traceable calibration standard is a select grade of material that is individually measured and certified. The quality is higher, with fewer defects than would be found on the ordinary calibration specimen. Each piece is individually measured against a transfer standard previously measured by a national laboratory, which has certified that the measurement value is traceable to the international meter.

Our certificate of traceable calibration:
  1. describes the measurement procedure,
  2. identifies the calibration standard used and its uncertainty as stated by the national laboratory,
  3. summarizes the measurement results,
  4. and provides a statement of uncertainty for both the individual and average values. The uncertainty statement is given in a form that meets the international guidelines for expressing uncertainty of measurements.

In contrast, the calibration reference specimen is supplied with a non-traceable certificate which states the average pitch based on a batch calibration. A rough statement of uncertainty is given, such as "accurate to +/- X nm" and "standard deviation of single values is less than Y nm."
