Calibration is the determination of the correlation between an input and an output quantity. All measurement instruments, such as voltmeters, manometers, vernier calipers, etc., must be calibrated to determine the variation of its reading from the absolute quantity. In light measurement, different types of calibrations are required based on a number of photometric, radiometric and luminous color measurement applications. These calibrations are typically done by comparison of the measurement values of a calibration standard to those of the test device.
Gigahertz-Optik‘s calibration laboratory for optical radiation measurement quantities owns, uses and maintains lamps, detectors and reflectors based reference standards traceable to PTB, NRC, NIST and NPL. In Germany, the Deutsche Kalibrierdienst – DKD (the German accreditation institution) and the Physikalisch-Technische Bundesanstalt (the German national standard laboratory) offer an accreditation service for industrial calibration laboratories where the lab‘s calibration standards, calibration procedures and the stated re-calibration intervals are subject to audit. This accreditation ensures that the traceability of the calibration and the calibration procedure is on an absolute level. The DKD also ensures the international acceptance of its accredited calibration laboratories.
Gigahertz-Optik‘s calibration laboratory is DIN EN ISO/IEC 17025 accredited for the measurement quantities Spectral Sensitivity and Spectral Irradiance under Registration Number DKD-K-10601.
