Gird sag import

Question

Hello,
We want to import interferometric measurement into Optic Studio. We have an internal procedure which use a dat file and import into grid sag surface to see the defromation of the ray propagation. This procedure does not work now. I added in attachement zmx file to show that no defromation is observed on image WFE.
Is any method to insert directly Mx measurement into Zemax ? Can you maybe proposed an other method to perform WFE analyses from measured surface?
Best regards,
Alexandre

Hello Alexandre,Thanks for your post here on the forums!It seems that you didn't see the wavefront error, because the surface aberrations are rather small, in the order of 10^-4 mm, and thus the wavefront error compared to the reference speher is small. Looking at your system it seems that it is not an imaging system but an afocal one. In this case it is better to use a reference plane for the wavefront instead of the reference sphere. You may achieve this by changing to afocal mode. Once that's done, you will see the wavefront aberration of the surface:You may read more about the Afocal Image Space properties in the Help file at:The Setup Tab > System Group (the Setup Tab) > System Explorer > Aperture (System Explorer) > Afocal Image SpaceI hope this helps, but if you have further questions, please let us know and we will be happy to help!Best,Csilla
