I don't quite understand why you guys are so worried about fluorescence... when it happens it decollimates the light so that it basically becomes like a lightbulb.

That, and some of the energy is also absorbed into heat, so I don't see how it could cause issues (though I wouldn't recommend staring at your fluorescing object either...)

Fuck, shipping is 30 bucks to my location. So much for cheap goggles :/

BTW I have blue T-REX goggles for my 638nm. The dot isn't visible on a wall even at 415mW. It does let 650nm pass right thru so don't use it for that color.

Wow, I ordered these thinking to see whether you guys were right about them or wrong. I ordered two pairs, and both nearly completely block my 100mW 405nm and 1.4W 445nm lasers from going through them. Shining the beam through focused to infinity, focused on the goggles themselves, and on where it would focus on my hand, and none of them are even brighter than my >1mW red pointer. Both of my pairs do this consistently, and I can focus the dot perfectly with them on, the dot itself being a yellow color. I doubt it was a one time thing for them to work, because I ordered a cheaper "used" pair and a new pair and both work flawlessly. Just my two cents as the new guy on the forum :beer:.

I was using these glasses myself when playing around with my 1.3W 445nm and I could barely even see the focused dot, let alone the light surrounding it.

Could anyone tell me if the beam from a 1.2w 445nm laser would be visible with these glasses?

EDIT: Yes, it (the dot) would be visible (the beam would not). I think one of the first tests I did was with a 1.2watt 445 from Survival.

The beam WOULD NOT be visible. Nor should be visible with any proper safety goggles.

The dot is another story, and would be visible.

tsteele93 that is what you meant I assume?

Yeah, IE is correct. I was skimming too fast. The DOT would be visible, not the beam. Thanks for catching that! :eek:

Would a beam be visible with a pair of laser safety glasses which have a high visible light transmission? for example the Eagle Pair® 190-540nm Standard Laser Safety Goggles (http://www.survivallaser.com/Eagle_Pair__190-540nm_Standard_Laser_Safety_Goggles/p556088_2780808.aspx) ?
I doubt it, but if you are interested in viewing the beam consider this - almost no one here uses goggles 100% of the time. There are situations that most members consider acceptable to drop the goggles for temporary use.

For example, if you are in a safe situation outdoors at night. Beam viewing is what that is all about! So you don't wear googles, (edit - GOOGLES - I crack myself up!) but you are VERY CAUTIOUS to make sure that...

A. No laser beams in flight paths;
B. No laser beams that could shine in anyone's eyes short of NOHD (which should be generously calculated with lots of headroom.)
C. Extreme caution regarding accidents like dropping the laser or having it fall from a mount or tailstand.

Basically, if you are shining a high power laser at night, outdoors and using GOOD common sense, it is considered (by many) acceptable to use the laser without goggles. Viewing the beam outdoors at night is one of the more rewarding aspects of laser pointers for many of us.

Now if you are indoors, a laser of that power is going to require goggles. I know some on here have used them without goggles, but it is pretty much a huge gamble at that point. If you catch the wrong reflection off of something that is not matte, you can easily damage your eyes in fractions of a second.

You will still be able to see the dot indoors with goggles. So you would use the goggles for things like burning or popping balloons, etc... Goggles actually help you focus the laser as well. It is almost impossible to stare at the dot on a wall at those powers, but with goggles you can look and see much more clearly as to whether you are focused tightly.

I hope that helps. If I am overlooking something, please anyone feel free to step in - I'm thick skinned and I'd rather have correct info than worry about whether I am right or wrong.

THAT SAID, I know some people may take a more cautious stance than me - so I will add that those are the precautions that I TAKE and they may, or may not be the same as you want to take. :beer:

[...]I think a lot of the people who come here are young kids who won't buy safety goggles if they see them as too expensive.[...]
THIS SO MUCH

I had no idea I was gonna have to dish out $150+ to get a laser that simply could burn, and now I'm looking at needing goggles too. I'd expect it to be a bit of plastic (almost free) in a mold (a little cost there) and some dye or film (most expensive part, but still dirt-cheap). Overall, I'd expect them to cost no more than $5-10 to produce, and after brand-name markups and packaging and such I wasn't expecting to have to pay more than $15-20 for goggles.

Then I see something about "the best goggles for under $100" in someone's signature. WFT?!?! I'm already paying an outrageous amount for a laser, and I have to get a special battery, and a special charger, and now you want me to pay another ~$100?? SERIOUSLY??

/rant

Anyways that's how I feel about it. Having something is better than nothing, and just because I'm cutting, say, 90% of costs in this particular aspect of safety doesn't mean I'm cutting 90% of the safety. Common sense doesn't come with the goggles, they are merely a tool to apply common sense. And, common sense is free, and advice is (usually) free as well.

- - - - - - - - - - -

On that note, I will definitely buy a pair of these if I get a burning laser.
