Calibration of current sensitivity

Gigahertz-Optik’s optometers are built around precision multi-gain range current amplifiers to process the light detector signal. All optometers are calibrated and certified using a variable current source which itself is calibrated by an outside accredited calibration laboratory. Correction factors are calculated based on the calibration values and used to adjust the display readings at each gain range. This current calibration is offered as a re-calibration service for all of the different Gigahertz-Optik optometers. Calibration uncertainty and traceability information is supplied in the factory calibration certificate.
