I have a model for which the image simulation outputs an overall greenish/blueish image when polarization is used, while I could not find any reason for why the red component would have lower power.

Here is the image with no aberration and no polariztion (with wavelength 1+2+3): 

And here is the result when polariztaion is enabled (still no aberration) : 

On the other hand, I could not find any anyslis that shows a wavelength dependency ; 

• relative illumination is the same for all wavelength, across all field
• transmission vs wavlength is the same for all surfaces

Is there a way to investigate further the wavelength dependency of the image simulation/polariztion of the design ?
