During the first 500-600 working hours, we recommend performing a spectral calibration every
50 operating hours.
After the first 500-600 operating hours, a calibration of every 150 working hours suffices.
Other factors that indicate the need for a spectral calibration: unsatisfactory illuminant
generation, the aberration of the intensity values, or a spectral curve that does not fit with the
predefined standard illuminants of the corresponding preset.
•
the spectrometer works correctly
•
the spectrometer settings are correct
•
all LED channels work correctly
•
the dark measurement is correct
•
your measurement environment is correct
•
your ambient temperature is correct
How to perform the spectral calibration is described in the iQ-LED control software manual.
4.4 Low intensity use
When using your system with very low intensity, the spectral measurement values will start to
fluctuate. The lower the intensity, the higher the fluctuation. The generated light is still stable up
to a certain point. The fluctuation of the values is caused by the noise of the spectral
measurement of the internal spectrometer. The light intensity will continue to get lower when the
influence of the noise continues to get higher. When using standard illuminants with an intensity
lower than 25 lux, it will no longer be possible to get a correct value.
