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 the lens on the lpm and see what the mw reading is.
Thanks for reading.
And have fun trying this
