Re: Part II: Getting Ready for High Brightness LEDs & the Light-Enabled View of Tomorrow

After reading back a bit, while there's nothing much else going on...

Regarding IR and UV LEDs -- if you want to get really technical (trying to approach diminishing returns on the whole "predictable results" curve) you will probably also want to search for a nomograph on the propagation/attenuation versus frequency of radiated energy passing through the atmosphere. Those propagation curves are seriously non-linear, involving a wide range of opacity/transparency across the electromagnetic spectrum. Personally, I remember being a bit surprised (mostly because it should have been obvious) when someone pointed out that a lightning strike emits a huge amount of xrays -- generally without much effect (other than causing most of the ozone smell after a strike) because the atmosphere absorbs xrays so effectively.

So your IR and UV propagation distance CAN be calculated with some precision.
