Measurement data
After a goniometer measurement is complete will the
following results be displayed.
1. The angular light distribution shows
the amount of light of the non-rotation
symmetrical part of the light source.
This field distribution is used to
calculate the beam angle.
2. The complete integrated spherical
spectra is shown in the spectra
window. Integrated spherical spectra
means that it is a spectra that is
created based on all the radiated
spectra’s in all angular direction
measured, this means that the
displayed spectra will be equal to that measured using an
integrating sphere.
3. The complete integrated spherical spectra calculated in
step 2 is used to calculate the complete
luminous flux in lumens.
The peak output in candela is also
displayed, which is the highest level of light output
measured during goniometer measurement.
4. The power is measured by sampling
voltage and current at a rate of 50.000
samples per second to ensure high
resolution and thus high power precision.
