In ZEMAX, the position of EXIt Pupil is given relative to Image Plane. If you wish to measure the EXIT pupil position relative to the first surface, you can use EXPP and TTHI. TY{? 4 3 T#3<gqM[ For example, if your first surface is Surface 1 and the last surface (image surface) is 10, you could set ?[|4 QzR CEJG =*3 TTHI with Surf1 = 1 and Surf2 = 10 and define EXPP in the merit function editor. Using SUMM to add the values retunred by these two operands you will be able to get the relative position of EXIT pupil to surface 1. 5'}!v tGy%n[ \

:c>,=FUT You could check "Scan Type" setting under Field Curvature/Distortion curve to either scan across x or y direction. In addition, you could use Grid Distortion, which give you an overview of distortion. Gu-Sv!4p Nb6HM~ For coma, it normally displays as a parabolic curve in Ray Fan plot but it can be a bit complicated to analyse if you also have other dominating aberrations. Another way to look into coma is by looking at Zernike Standard Coefficeint, the term 5 and 6 correspond to coma in y and x orientation respectively. ZERN operands should help to extract these values. #{(rOb6H) [3s~Z8
pP However, these are only for the third order. Once you go higher order aberrations, the conversion between Seidel and Zernike becomes not so stright forward.
