WebDichroic extinction is the most likely polarization mechanism because it is consistent with the various available extinction estimates. In this case, a highly ordered, coherent toroidal magnetic field must be present in the obscuring structure close to the nucleus. WebA dichroic filter /mirror and usually two additional band-pass interference filters, together making up a dichroic filter cube, are used to separate the excitation wavelengths from those emitted. A dichroic filter reflects light of short wavelengths and transmits light of higher wavelengths.
