I want to use my IR video setup through the glass walls of the aquarium,
rather than dunking the (waterproof) video camera in the aquarium. It
occured to me, however, that perhaps infra red light does not succesfully
pass through glass. I found this interesting article
which explains that relatively high wavelength infrared light (just a
little bit longer than red light) does pass through glass, but low
wavelength infrared light doesn’t. I’m pretty sure that’s okay. Based on
this person’s discussion, most commercial products use light from the
higher end, and these seem to pick up fish just fine.
