Hi,


I was trying to calculate the efficiency for user defined surface: us_hologram_kogelnik;


I followed the manual and it works fine when the construction is



 



 


However, when z2=-23, the efficiency reduce significantly and the plot was like:



I’ve already move the image surface to the focal plane. I don’t know if it is correct.


Please help me.
