Calibration ensures that the optical power meter provides accurate measurements by establishing a relationship between the meter's readings and known optical power values. This is typically done by comparing the device under test (DUT) to a working standard, which is itself calibrated against a reference standard traceable to a national metrology institute such as NIST (USA), PTB (Germany), or NPL (UK) under defined conditions . The calibration chain ensures international recognition and traceability of measurement results.
Manufacturers like Keysight offer special calibration services for optical power meter heads, including enhanced linearity, responsivity versus wavelength, and spatial homogeneity measurements. These calibrations are performed in metrology-grade laboratories and provide the lowest measurement uncertainties . Periodic recalibration is recommended to maintain accuracy over time.
