Non-sequential Zemax analysis of the proposed optical implementation after the Lyot stop to split the two circular polarizations. Left: the polychromatic ray tracing (650–900 nm) for one polarization, and right: the detector view of no-coherent intensity distribution in logarithmic scale. With these classical materials (MgF₂, quartz, infrasil) the maximum scattered light is 10^-6 of the residual coronagraphic intensity. In this simulation, we chose an anti-reflexion coating of 0.5% per surface.
