Just finished watching episode five of Asimov's Foundation (it's on Apple TV), and there is a scene where a character exits a ship and switches a space suit visor over to Infrared to find a planet that does not appear in the visual part of the spectrum, nor on a ships navigation display. This is the first time I can recall any sort of Sci-fi using narrowband. Perhaps it was done on Star Trek Discovery.
