Still. Dragonlasers has already said that they will protect you for a few seconds with the high powerd lasers. They are made for accidental stuff.
I've tested my glasses with both my Viper 75mw that's able to light matches. And my Aurora 150mw. None of them got through the goggles. Not one bit.
I also tested to keep camera on the other side, as I thought. No IR light (due to filter). Still, the "dot" of the lasers can be seen as yellow when using them normally.

can you see a yellow dot when you wear glasses and points the laser on a white surface?

Sure. I see it.
I tested the "does any light go through" once again with my 150mw Aurora. Nothing went through.

I have just recieved a pair of Eagle Pair laser googles to use with my red lasers.
Silly question but should i be able to see any of the red dot when viewing with the googles on? I cant see any sign of the dot or beam when wearing them.

my laser blocks 100% of the light or near 100%. when i put the glasses in front of my 300+ mw laser there is no green dot at all. i see the laser beam being deflected and a lot of yellow light is given off.

when i view the dot of the green laser while wearing the glasses it appears yellow.

sorry if my last post was confusing. i'll try and post some pics if you guys want.

What you see is the fluorescence, I even saw it with goggles rated D 532nm L6, IR 532nm L8. That's an OD of 8 minimum. You don't see any output of the laser, only of the fluorescence of the material it hits. This is longer in wavelength and much lower in intensity, so don't worry about it. It can even be very usefull for alignment.

I know what your talking about, what looks to be a "white" spot, but this (the glasses that the thread starter said) is 532nm being let through. I have the same filter with my glasses, it's an orange/red color. Though what passes through only seems to be about 1mw 532nm with a 100mw source. So your still safe even with a direct hit for a couple seconds. At least with a 100mw source.

I don't like safety glasses that completely block out the green light leaving that "fluorescence" light coming through as it's very dim.

Am i missing something, or is this impossible?

if you see the dot after the googles it means that some of the green light is passing, believe it or not xD

Yes, for definition lasers emits waves of identical frequency and phase, if you can see a dot of a 532 nm laser through the glasses, then it means that some green light is passed :)

Not necessarily. When the light hits some objects and the objects absorb some of the light, they are radiated back out in a different wavelength. This is what you call fluorescence.

Yes, but the light for hitting an object must first reach it, if a coherent light is blocked completely by an appropriate filter can't emit fluorescence!

I'm not sure I under stand what your saying. I'm just saying that if it hits an object and the light radiates back at a different wavelength then the glasses wont block this (or not as well) as they are meant for 532nm.

Wait....... Maybe your thinking I'm talking about the filter actually emitting fluorescence.. Maybe both of you lol. If so, yes you are both correct. I'm talking about objects on the other side of the view. Not the actual filter.
I hope I'm finally on the same page as you now. If I was the one that got off I'm sorry.

I understand... I was talking about a laser beam which passing through the safety glasses while you were speaking of a light that become visible (fluorescence) by someone who wears glasses :D :D
