High-precision optical power meter calibration in Norway

Optical power meters in Norway can be calibrated through accredited laboratories such as Justervesenet, LASER COMPONENTS Nordic, and Trescal, following ISO/IEC 17025 standards and traceable to national and international standards.

Calibration Providers in Norway

Justervesenet (Norwegian Metrology Service) offers calibration by substitution against standard detectors, ensuring traceability to national standards and providing documentation for each calibration performed.

LASER COMPONENT

S Nordic provides calibration services for laser energy and optical power meters, emphasizing traceability to international standards such as NIST, ISO, or DIN. They distinguish between calibration (measuring deviation) and adjustment (aligning the device to a standard) to maintain measurement accuracy. Trescal Norway operates ISO/IEC 17025 accredited laboratories, including a facility in Bergen, offering calibration and repair services for optical and energy measurement instruments.

They provide traceable certificates and fast turnaround times, ensuring compliance with international standards.

Calibration Procedure

Calibration of optical power meters typically involves comparing the device under test (DUT) to a working standard with higher accuracy. The working standard is itself calibrated against a reference standard, which is traceable to a national metrology institute such as Justervesenet in Norway, NIST in the USA, PTB in Germany, or NPL in the UK. This ensures that measurements are internationally recognized and reliable.

Key steps include: Preparation: Ensure the optical power meter is clean, stable, and within operational conditions. Comparison: Measure the output of a known light source with both the DUT and the working standard. Deviation Recording: Document the difference between the DUT reading and the standard.

Certificate Issuance: Provide a calibration certificate detailing the measurement uncertainty, traceability, and conditions of calibration. Standards and TraceabilityISO/IEC 17025 accreditation ensures that laboratories meet international quality and technical standards for calibration. Traceability to national standards guarantees that measurements are consistent with international units (SI), allowing reliable comparison across laboratories worldwide.

Calibration intervals are recommended based on usage, manufacturer guidelines, or ISO 9001 requirements to maintain measurement accuracy.

Additional Considerations

Automated calibration systems, such as EXFO's IQS-12002, can streamline the process, reduce human error, and provide detailed documentation for optical power meters, attenuators, and OTDRs. Calibration does not adjust the device unless an explicit adjustment procedure is performed; it primarily quantifies measurement deviations for accurate use. Certificates from accredited labs are essential for compliance in industrial, research, and quality-controlled environments.

By using accredited services in Norway, optical power meters can be reliably calibrated, ensuring accurate measurements for scientific, industrial, and telecommunications applications.
