Hi ! Its been a long time i last posted on the forums.
I am trying to experiment with a few optic fiber strands i pulled apart from a show piece.
which looks something like this :-
I tried passing IR light through the optic fiber but i don’t see illuminated dots at the other end. That is, the IR light doesn’t seem to be traveling through the fiber.
Is the fiber limited to a certain(visible) range of wavelength of light ?
Are there any cheap fiber optics available for IR ?
