January 15, 2024 – Andover, MA – MKS Instruments, Inc. (NASDAQ: MKSI), a global provider of enabling technologies that transform our world, is pleased to announce that the company has received ISO/IEC 17025 accreditation for its Ophir® Photonics Darmstadt, Germany Calibration Laboratory. ISO/IEC 17025 is given to calibration laboratories that have achieved the highest standards of quality, administration, and technical operations, thereby ensuring the highest accuracy, as measured by the National Institute of Standards and Technology (NIST). The scope of the accreditation covers MKS Ophir’s photodiode, pyroelectric, and thermopile laser power and energy sensors, as well as its power and energy displays and virtual meters.

All of MKS Ophir’s Calibration Laboratories are now ISO/IEC 17025 accredited: Jerusalem, Israel; North Logan, Utah; Omiya-ku, Japan; and Darmstadt, Germany. Accreditation gives customers increased confidence in MKS’ testing and calibration methods and its personnel, improves the validity of test methods, and provides the best traceability of measurements and calibrations to national standards.

“The ISO/IEC 17025 accreditation of all our international labs validates Ophir’s 40+ years of dedication to the highest standards in the field of calibration of laser power and energy measurement,” said Reuven Silverman, General Manager, Ophir Photonics. “Accreditation provides further confidence to customers of our NIST-traceable series of measurements, which is especially important for government and industrial organizations.”

Markus Schmiedt, Manager of the European Calibration Lab at Darmstadt, Germany, stated, “European customers that are required to have the re-calibration done by a lab with ISO/IEC 17025 accreditation benefit from shorter lead times as their equipment does not need to be shipped to international labs. Calibration certificates issued in our European lab will now automatically carry the ISO/IEC 17025 accreditation.”

ISO/IEC 17025 accreditation ensures that Ophir’s calibration laboratories operate under controlled and approved working procedures, the equipment and calibration standards used are regularly calibrated by other ISO/IEC 17025 certified, and NIST traceable laboratories and the uncertainty values communicated to customers have a solid foundation based on rigorous experimental and statistical analysis.
