I found some on Laserglow...and I had a few questions.

http://www.laserglow.com/AGS#

1: What does 'optical density' mean, and is it worth the extra money to buy 7 instead of 2?

optical density is the amount that the glasses protect by, OD1 is 10% of light gets through, OD 2 is 1% etc. OD7 will let through only 1/10 000 000th of the light

2: Does it ruin the spectacular-ness of the laser? Dim beam, smaller dot, less visable light, not as bright, etc?

yes of course, u will only see a tiny dot and at OD7 maybe not even see it at all...(definitely no beam, dot will also appear whiteish depending on glasses)

3: How do I know if it's working?

the laser will appear extremely dim

4: How much power does it cut when shined through the glasses? Will it take it to a point where I can shine it in my eye purposely and nothing will happen?

no never shine a laser in your eyes even with glasses on, they cannot with stand for long to a highpowered laser, and some power will still come through

5: Why do they have glasses for almost every wavelength except 405nm? (their other type does, sport is only 532, and 660)

not sure...

6: And lastly, what do you guys recommend as far brand for laser safety goggles? Any good ones out there? That won't cost an arm or half a leg? I'm looking at around 50-90...not $200!

i reccomend dragonlasers, they have a pair that does 405nm and 650nm for $50 shipped i think

Thanks for all yall's help!

Are there any glasses that you recommend so I can still see a beam, and dot, but it's still protective? Especially for 532nm, since it's so visible, will an OD2 be good enough to be safe, but still allow a beam...on say..a 50mw? What about a 200mw? Or is that something that requires testing?
