May 8, 2012 — Coherent Inc. (NASDAQ:COHR), supplier of laser power and energy management instruments, achieved a certificate of accreditation to ISO/IEC 17025:2005 at its Wilsonville, OR calibration laboratory, demonstrating technical calibration competence and operational conformance with a laboratory quality management system.

The accreditation applies to the company’s pyroelectric laser energy sensors, thermopile laser power sensors and meter electronics.

ISO 17025 governs a laboratory’s quality management system, such as auditing and corrective action processes, and requires adherence to rigorous technical requirements. These requirements include methods for determining measurement uncertainty, validating the appropriateness of test methods, and providing calibration data to customers in an approved format.

Coherent’s compliance was independently verified through ACLASS, a brand of the ANSI-ASQ National Accreditation Board, and recognized internationally by ILAC, APLAC and IAAC. The certification enables organizations in medical, military, or other government-regulated industries to document the traceability and performance accuracy of their products, and for any customer to eliminate supplier audits.

Coherent offers a diverse portfolio of laser sources, laser tools and laser accessories for a broad range of commercial and scientific applications. Learn more at http://www.coherent.com/.
