How much IR from 532nm before finger gets really hot

[dubious speculation]

If it's only "mostly" blocked, you need new goggles

i said that because most goggles for 532nm block approximately 99.99% of the green, so i would've been incorrect in saying that the goggles would block 100% of the 532nm wavelength,

please feel free to correct me if i said anything that is innacurate

cheers, will

My 60W Co2 laser feels like the sun on a sunny day on my hand , warm ( large beam area )

are you nuts? how large a beam area? I ran a piece of white leather under mine.. not pretty. my fingers don't go under beam

You shouldn't shine a laser on your skin if your not sure of its power, and certainly not anything class 4, be extra careful with blue lasers, I burned my right thumb when I was holding the laser in one hand and my camera in the other and it slipped and I managed to avoid dropping the laser but my thumb was over the end for a second, well I should have dropped the laser, from now on I have both hands free or I put the laser down and hold the camera with both hands. It seems like it goes through your skin and burns inside, its been two weeks now and my thumb still has an odd feeling when I touch it so be careful. Also consider a large or extended focus knob on powerful lasers to help avoid burning yourself.
