Hey everyone
So the other day I was shining my 250mw red laser out my bedroom window on the ground when suddenly ahummingbird flew right at the window to investagate the dot!!has anyone had THAT happen to them?
Hey all
I see that there is a lot of talk of the safe viewing of the dot of a 445nm laser at 10 feet or so. Now idont know the focal length or lens diameter of the human eye but maybe someone with an lpm can try this.
Get a small lens shine the laser at the ceiling and focus the dot though...
