Has anyone used a Wet mate mini dome or an air dome with a micro 4/3?

I am not quite clear about the physics behind it so I wonder if anyone has tried a wet mate like the Nauticam one or a similar solution with a flat port on a macro 4\3 to restore the air field of view???

I have now and it works with a +1 or +2 diopter will post some examples

Tests are here
