Eyewear for 10W laser

[brent113]

If you’re interested I detailed some of the calculations for the 1.6W here

Best options for eye protection?

I see my post from above where I did the calculations was removed. Oh well, here it is again: 1600mW with the provided OD1.19 goggles will reduce laser energy down to ~100mW. With an assumed large beam divergence of 35mrad that would put the Nominal Ocular Hazard Distance (NOHD), which is defined as a beam intensity of 2.5mW/cm2, around 10ft with the goggles on for a direct hit. (Without goggles or any protection that NOHD for a direct hit would be ~40ft) With wood and similar materials the la…
