ISO 17025 Accreditation

Coherent’s Wilsonville, Oregon; Dieburg, Germany; and Tokyo, Japan calibration laboratories are fully accredited by the ANSI-ASQ National Accreditation Board (ANAB) and recognized internationally by ILAC, APLAC, and IAAC. Certification to ISO 17025 is a formal recognition that a calibration laboratory is using valid and appropriate methods and is competent to carry out specified tests or calibrations.

Scope of Accreditation

The scope of accreditation applies to the laser/electrical calibration of nearly all the company’s catalog pyroelectric laser energy sensors, thermopile laser power sensors and meter electronics. within the ANAB website at

ISO 17025 governs a laboratory’s quality management system, such as auditing and corrective action processes, and requires adherence to rigorous technical requirements.

Technical Requirements

In terms of technical requirements, ISO/IEC 17025 ensures that a company:

  • maintains testing facilities and equipment to specified standards
  • ensures protocols are fully documented
  • trains workers to an appropriate level of competence
  • confirms validity and appropriateness of methods, especially so-called “non-standard” methods such as those used to calibrate laser measurement equipment, which have been developed internally
  • uses accepted mathematical methods for calculating results
  • verifies that purchased test equipment meets proper requirements and that all equipment used to produce accredited calibrations has itself received ISO 17025 accredited calibrations
  • has a traceable path of calibration to independently maintained national or international standards
  • provides both as received and outgoing testing data to customers in an approved format
  • ensures the calibration certificate meets the requirements of the standard
  • The outcome of all these efforts is that customers can have confidence that a laboratory achieves verifiably correct results and that these results will be reported in an unambiguous manner.
