High-precision optical power meter calibration in Bosnia and Herzegovina

The Institute of Metrology of Bosnia and Herzegovina (IMBIH) provides traceable, high-precision optical power meter calibration services compliant with international standards.

Local Calibration Services

In Bosnia and Herzegovina, IMBIH serves as the national metrology institute responsible for establishing and maintaining state standards, including traceable calibration of measurement instruments such as optical power meters . IMBIH ensures that all calibrations are traceable to SI units and recognized internationally through the CIPM Mutual Recognition Arrangement (MRA), allowing certificates issued in BiH to be accepted globally . The institute operates laboratories for electrical quantities, time and frequency, and other metrology fields, providing calibration, testing, and reference services to industry, research, and calibration laboratories .

Calibration Procedures and Standards

High-precision optical power meter calibration involves comparing the device under test (DUT) to a reference standard with superior accuracy. The process typically includes:

• Responsivity calibration: Measuring the DUT's response across relevant wavelengths (commonly 850, 1310, 1550 nm for telecom applications) using reference detectors such as electrically calibrated pyroelectric radiometers (ECPR) or cryogenic radiometers .
• Linearity and uniformity tests: Ensuring the meter's response is consistent across its measurement range and detector surface .
• Environmental control: Maintaining stable temperature and humidity during calibration to minimize measurement uncertainty .
• Connector and fiber considerations: Calibrating with the same fiber and connector type as used in actual measurements to avoid reflection-induced errors . IMBIH laboratories follow ISO/IEC 17025 quality management systems, ensuring that calibration results are reliable and reproducible . They also participate in EURAMET intercomparisons to validate competencies and maintain international equivalence.

International Traceability

IMBIH's calibration services are linked to international reference standards, providing traceability to national metrology institutes such as NIST (USA), PTB (Germany), and NPL (UK) . This ensures that optical power meter calibrations performed in BiH meet global accuracy requirements, with documented uncertainties and compliance with recognized standards.

Practical Considerations

For organizations in Bosnia and Herzegovina seeking high-precision calibration:

• Direct IMBIH services: Contact IMBIH for calibration of optical power meters, including traceable certificates and uncertainty analysis .
• Subcontracting to international labs: For specialized calibration or extremely low uncertainty requirements, meters can be sent to accredited international laboratories with NIST or equivalent traceability .
• Routine maintenance: Regular calibration, cleaning of connectors, and verification against reference sources are essential to maintain measurement accuracy . By using IMBIH's services, companies and research institutions in BiH can ensure high-precision, internationally recognized calibration of optical power meters, supporting telecommunications, industrial, and scientific applications.
