Need help on what i believe to be a physics effect?

Question

I believe in physics theres an effect in which if a glowing solid material is placed behind a translucent/transparent material then you can see through both material as if they were both translucent/transparent. Any ideas? please add sources if you can find any! thanks!

This sounds a bit like a misunderstanding of the operation of an old style grease spot photometer, used to compare the intensity of known and unknown light sources, which you adjust until the spot 'disappears':

I've never heard of this (I've been working in physics over 40 years!). So I think there is no such effect.

There is no reason a glowing solid material would allow an external light to pass through it.

(I'd love to be proven wrong though.)

I don't know of any experiments directly; but there definately people looking into the use of polarization panels which would have nearly the same effect.  Then too I think we have both heard of people working on invisability projects.
