Hello,
I want to know if safety glasses are needed if you only point a 1 watt green laser into the sky? every website talks about direct and indirect exposure but it doesn't specify what type of indirect exposure to the laser light. If you are holding the laser and then point it into the sky away from you and you only look at the beam going through the air is there danger of eye damage?
Nobody talks about this. They only talk about "don't point it at aircraft" or "don't look directly into the beam" ...duh of course I wouldn't. Also they talk about don't even look at the spot on a wall the laser is hitting. Of course, yes I know that. That's not what I'm asking.
I know the light is only visible when reflecting off of dust particles or the humidity or the air itself. The question is on a 100% humidity and very dark night can the beam itself, viewed going past you from the side, be enough to cause eye damage. If so what are the mW strenghts for 532nm light that this starts to become a problem for the user.
The 2nd question I had is for cheap green lasers that emit infrared light does that infrared light stay within the visible green light beam, or does it diverge like a flashlight?
