Are these goggles good enough?

[Flugufrelsarinn]

I do not have a brand name for them as I bought them two years back. But they do say 532nm on the inside of the rim. In addition, when I shine my 5mW DX greenie into the lens (WITHOUT IT ON MY FACE of course ) nothing comes thorough. I am asking because I want to be protected from the diffuse reflections from my new 200mW green laser when focusing it.

Thanks.

Yes, they're probably fine. From where did you buy them? Pictures might help.

Oh okay I found the brand name. They are by "Orbtronic" I don't see any OD/L numbers and all it says on the rim is 532mm 190-540mm. I did try focusing my 200mW laser with it and it made the "dot" appear as small as a orange 1mm diameter dot. About the size as a full stop on this web page. I hope I didn't put my eyes in jeopardy "testing" these out.

If you didn't hit your eyes you're fine, just check if your goggles are still fine after being hit with 200mW.

What? Since when is it a concern that the goggles are still fine after being hit by 200mW? It's your eyes that matter here, not the goggles. The goggles could pass all the light through them into your eyes and not show a single sign of damage; is that supposed to be an indicator of a good pair of protective goggles?

Flugufrelsarinn:

You should get some goggles that are known to be good. It's fine and well to say that you'll only be observing diffuse reflections, but what if there is an accident? I know first hand about not realizing that there were specular surfaces that my laser beam has bounced off of; the beam went straight in my eye and were it not for my safety goggles it would've blinded me. A 5mW laser not passing through the goggles means nothing; whether it protects you against your 200mW laser is the important part.

Your goggles are probably the standard red laser enhancement goggles, that happen to be pretty decent against green. Who knows though, so please post a photo of it. Beware that these red goggles don't protect at all against the IR that green lasers produce, so you should still avoid all specular surfaces even if the goggles are sufficient for protecting against 532nm.
