Hi @Luca.cellerino!

The properties of the objects can be called in the multi-configuration editor using the NPRO keyword:

Unfortunately, the source properties are not available there.

In one of our examples, we had different sources with different wavelengths and we were optimizing on the source power. I don’t know if that could be an option for you.

Hi Luca,

There is a very convoluted way of setting the Tri X and Tri Y values as variables but you have to use a mix of the MCE and 2 ZPL macros.  The thought process is as follows:

• Use a dummy object to control the TriX and TriY values (use X Position and Y Position); this dummy surface will be the variables the MFE will optimize
• Use the MCE with NPOS 1/1/4 & NPOS 1/1/5 to read in the X Position & Y Position in the MCE; these cells will have ZPL solve on them...the ZPL solve will:
  • read in the X/Y Position using NPOS
  • use SETNSCPROPERTY with 181/182 to set the Tri X & Tri Y on the Source Radial
  • return the Tri X & Tri Y value with a SOLVERETURN (this can be any value but you have to have a SOLVERETURN so might as well be the actual Tri X/Y value)
• Use the MFE with NPXV & NPYV to target the desired Tri X and Tri Y value

Hi Michael,

Excellent I would say, I can integrate this workaround into my system and make it look for the appropriate values of emission x and y to obtain the chromatic coordinates of luminance on my target.

I try.......…

Thanks

Thank you @MichaelH! Tricky but yes it should work.
