Infrared doesn't pass through windows.
actually thats UV. transition lenses won't change with a glass window thats not open. infrared is basically heat and does indeed pass through. Cars in the sun would not get hot so fast if they did not let in infrared.
I have an IR camera and windows look like mirrors. Might depend on the type of glass idk.
if this yahoo from the internet I found in a search is right then its both:
"Glass will bock low frequency IR (red hot), but allow the passage of high frequency (white hot) IR. Hence, the heat of the sun will easily pass into a greenhouse, but once this energy is converted into low frequency heat by the objects within that absorb it, then the resulting low frequency heat is trapped. Hence, the Greenhouse Effect."
That makes a lot of sense, thanks for doing the homework!
Some UV is blocked by glass. Either UVA or UVB. It doesn't block both.
yeah I encountered it when looking at infrared for another convo in the thread. its uvb for what we think of as glass. the clear stuff. which is what causes sunburns and the transition lenses to activate.
I'm not going to argue with you but you should read the article perhaps? It's pretty specific about where the laser is aimed vis a vis windows and whatnot
