Is there a material that does not affect light?
Perhaps very thin glass, or another material for example? It would have to have the same index of refraction I imagine. Any help would be greatly appreciated!
I'm interested in putting a material into an optical system that would hopefully not affect the system. I dont think this is possible, and from the explanation listed below, that seems to be a good guess that it isn't possible.

if youre talking on a technical scientific level, it would have to be 100% invisible, not just invisible to the human eye. on a small enough level, im sure you can see atoms. so i dont believe solid matter can exist without affecting light. the only matter that has no mass (theory btw) is gravity, and even that affects light.. (the reason blackholes are black). i dont know if there is. unless you mean what is visible to the human eye. .......... *reads update* oh.. ok. so if youre looking for something you can look through, now i get it a bit more. im still curious what you mean by optical system (another update on the question?). a very clear piece of glass that isnt concave/convex doesn't affect sight noticable by humans. a gas technically. and if its close to the eye, a thin net-like material affects vision to a minimal amount, and would not reflect light. yeah i think i got too sciency with my first explination.
