@FingerMcPokeye, nice diagram! that's my thinking exactly, so the Fesnel grooves, being circular, will produce radially polorized light, radial about centre of the Fresnel circle.
Now the thing is... the problem light rays are generated within the Fresnel lens... so... how is the light from these rays polorized? and are they're polorizes? and how would a filter, linear or circular differentiate between the incoming light and the internally generated light?
In any case, I still maintain that the only light that either filter would block is the uniformly polorised light because that's what both types of filter do... and I can't see that either type of light being emited is linear and there isn't a filter that blocks circular polorized light.
The circular polorizer emits circular light, it doesn't block it.
Anyway... I now have a circ filter so I'll try oit for myself (it would probably have been quicket to try it than type this!
@LZoltowski, I'm going to need a while to digest that!
