We all know that Lasers are dangerous gadgets. So I have a hypothetical question on how it all works.
If we all go back to when we were kids with a magnifying glass, we know the light beem has to be focused pinpoint beam to burn that ant!
We know a 100mw laser when pinpoint focused is more than capable of burning black tape or to cause injure the human eye.
If one had a 100mw laser..but focused to a 120inch beam at 100ft, would it be dangerous to look at from 100ft?
My way of thinking is something like this. Not taking beam signal distance losses into account
100mw/120in=.833mw per inch
I'm thinking the human eyes ..about 1 in wide would only be exposed to .833mw...each eye
Not a bright thing to do, but I would think it would not be harmful
There has to got be a math formula for this..
So, How does it work?
