<p>I have so far been unable to find a tutorial on constructing phase maps of surfaces in Zemax. (The closest thing I have found is a video tutorial in which the user imported a grid phase object and was therefore able to see the phase of the object imported.) I would like to be able to take an arbitrary slice normal to the propagation axis in a sequential optics simulation and capture it as a grid phase equivalent, either by exporting as a .zbf file or by copying the text output from the monitor. My expectation is that there should be a radial distribution of phase since the different rays travel different distances to reach the image plane and accumulate phase in proportion to distance travelled. I have attempted to view phase using two of the sample files: 1) Sequential>Objectives>Double Gauss 5 Degree Field.zmx and 2) Physical Optics>POP through a wave plate.zmx<br>In the former case, I always see 0 phase regardless of which surface I select:<\/p><p>       <\/p><p>In the latter case, I see a constant or nearly constant phase. Also, I don’t see any difference occuring based on which “Display>Project” option I select (i.e. “Along Beam,” “Along Normal,” or “Along Local Z”) :<\/p><p>             <\/p><p>Of course, in this case, I’m sampling at the zone plate, so there may not be much phase accumulation yet. However, I see essentially the same thing when I insert a surface between the zone plate and the image plane and sample at that surface instead. <br><br>Does anyone have any insight into how to retrieve the correct phase information across the beam cross-section or know where to find a tutorial on the subject?
