Reply To: Optic studio-zemax operand values are different from the plot (Genc and Denc)

Hi Elham, thanks for the reply. 

I thought that would be the case, but unfortunately, it seems like the GENC operand does not work effectively for hybrid models. This is the case even when I leave "Multiply by Diffraction Limit" unchecked and use very high sampling, particularly when I introduce disturbances to the segments.

My goal is to perform a sensitivity analysis (tolerancing) on our segmented telescope design to evaluate how sensitive Encircled Energy is to parameters like tilt, decenter, and radius of curvature (ROC). While the DENC operand provides results that are close, I’m uncertain about the reliability of the diffraction-based Encircled Energy results in mixed mode.
