Can someone here point me to some bacteria that glow when stimulated with IR light, or any kind of radiation?
The reason I need to know is I think it would be a real cheap alternative to conventional night-vision goggles. I have seen projects to that end that employ digital cameras with the IR filters left off the lens, but I am concerned that those projects have a latency that would make it difficult to function in real time.
I would also be grateful if someone could inform me of a material that would allow IR radiation to pass through, but block visible light.

Use sheets of these filters to block everything but near-IR. It will not help with the night-vision goggles problem though. (Unless perhaps you wear these goggles, use bright IR floodlights, and occasionally set off a camera flash to destroy everyone else's night vision.)
I would suggest trying the night vision scope Instructables (like cell phone camera one, for instance) and see how they do. Maybe the latency is not as bad as you fear.

By the way, fluorescence is not the solution to seeing IR. You have to consider the energy per photon. So some UV-absorbers can fluoresce in visible light, and some black materials can fluoresce with infrared light.
You might be thinking of the display screens in night vision goggles that fluoresce in response to energetic electrons spit out by the photomultipliers.

The black plastic there's on tv remotes block visible light but lets IR light pass through.
