There's also such a thing as an ultraviolet camera. Oddly, nobody seems to care about these as much. Here's the only example I could find.
I wonder if it would be possible to rig up an "expanded-spectrum" camera. Make the red channel be near-infrared, make the blue channel be near-ultraviolet, and leave green as it is (or expand it to cover the old red and blue as well.)
Seeing through the eyes of an alien, really.
