Hello,
I put a coating on a mirror. the phase of this coating is varying with the angle of incidence => it should introduce aberrations, but it does not, the wavefront error is zero, and MTF remains close to diffraction. with polarization raytracing on, or off.
see attached PPTX file
which parameter in the zemax calculation is wrong?
Thanks for helping!
Paul

Hi Paul,
My best guess is that you are using the polarization setting in the tool settings but not for the overall beam in the Polarization tab of the System Explorer. If the rays are set to unpolarized, the remaining tools won’t generally be able to distinguish polarization effect unless, like some, they include an independent polarization setting for the rays.
I’m not sure the MTF will change much even with the phase coating, but the Wavefront Map will.
