need clarification on armor types

[thecyclemania]

Hello fellow SE4 players,

I have a question in regards to armor type.

Can someone explain the difference between emissive armor, stealth armor and scattering armor.

Please be detailed in your explanation.
An example of effect on gameplay would be very helpful.

For example, stealth armor. Is your ship invisible or not ?

What about the armor that says "any damage below 10 is ignored". Does this apply to the first 10 points of damage (substracts from it) or it "absorbs" any damage of 10 or less. In this case, it would not work agains 11+ points of damage.

Thanks,
thecyclemania
