In my plots IвЂ™ve replicated the same offsets. This is likely done for improved visualization purposes. Lastly, OpticStudio applies a phase offset to each of the wavefront phase maps (compared to maps found directly from polarization ray tracing).

Not sure how OpticStudio goes about computing phase maps with a broader full scale. As a result, my phase maps are always constrained to have a maximum full scale of (-pi,pi), or (-0.5,0.5) in waves - this in turn means my phase plots display phase wrapping in different locations compared to the OpticStudio versions. This appears to be the same way that OpticStudio finds the phase as reported in the polarization ray tracing analysis output. Second, I'm computing phase in Matlab as atan2(Eimag/Ereal), which is the four-quadrant version of arctangent. So these pi transitions are not physical discontinuities (similar behavior occurs for guided-wave and laser modes, e.g., Laguerre-Gaussian modes). Nonetheless, the pi phase transitions for the Ex component occur in regions where the intensity goes to zero. First, the intensity profile for the Ex polarization is very weak, almost three orders of magnitude less than the dominant Ey component. These pupil maps are found by extending ray tracing from the image plane to the exit pupil reference sphere. For the simpler version of your model (i.e., the non-segmented primary mirror), this is what I obtain for all three polarization components: Also, it appears that OpticStudio has a way of computing the phase maps such that the full range of the color scale spans more than one wave.Д®) To explore some of the detail further, I wrote a ZOS-API Matlab script to use polarization ray tracing to re-create the wavefront phase maps as well as to generate corresponding pupil intensity maps. The phase transitions are more clearly defined now. In this case, here is the Ex wavefront phase map at 256 x 256 resolution: There are two types of abrupt phase changes present, namely: (1) pi shifts between different quadrants of the beam (corresponding to transitions between intensity lobes as shown below), and (2) 2pi phase wrapping transitions (which are not discontinuities).Д) For detailed polarization analysis, I would suggest you start with a simpler model, for example one with a continuous primary mirror defined in a fully sequential model. I simply opened your file, and this is what I get for Ex polarization at 0.619 um (source having Jx=0 and Jy=1): That being said, I'm using the latest version of OpticStudio (21.3.2) and don't see the same 'randomness' that you show in your wavefront maps. All segments appear to have the same coating. In general, the coating materials should be defined over the full wavelength range of interest, unless the dispersion is negligible.Д¬) It's not clear what the purpose is for using so many UDAs to define the segmented primary as a collection of nonsequential surfaces. Silicon nitride goes from 0.8 - 2.0 um, and Ag is only defined at 0.619 um. (You may want to add other values in order to span the full range of interest).Д«) The coating materials should have their properties cover a broader wavelength range. I took a look at your model and have a few comments to supplement what Mark has said.ДЄ) There is only one wavelength defined at 0.619 um.
