FGC100 Calibration Unit
The FGC100 calibration standard is a current and temperature stabilized LED source designed to calibrate the FluxGage system. The FGC100 includes a lamp unit and a controller unit. The FGC100 lamp unit emits at 2pi geometry. The FGC100 lamp unit is mounted on the FluxGage for calibration. A special fixture in the FluxGage cover ensures repeatable mounting and calibration.
The FGC100 is calibrated at Ophir from a NIST traceable calibration standard.
As the FluxGage system was design specifically to measure LED luminaires, by calibrating the FluxGage with an LED standard, rather than with a tungsten standard, several major calibration uncertainty contributors are avoided:
- Spectral mismatch between tungsten and LED sources
- Angular distribution mismatch between tungsten and LED sources
- Excess infra-red radiation emitted by tungsten sources, which contributes to stray light in spectrometers
Put simply: If you are going to measure LEDs, best to calibrate with an LED!
