I wouldn't want to be pointing a 1.2w 445 at a flourescent material without glasses, the dot it makes it's self if already REALLY bright, flourescent material makes it a lot LOT brighter, painfully bright without glasses.

If you want to toy with flourescently reactive things, I'd say pick up a 405nm laser (50mw will be more than enough), they're only $20 or so for a nice new wish pen 2xAAA host.

A thousand times this. If you want to make things glow a 50mw 405 which is relatively safe as long as you're not stupid will make things glow pretty well. Tonight I was photographing my 100mw multiline argon along with an 710mw 445nm and ~7mw 473nm together (check my thread in the multimedia forum for updates tomorrow ;)) and you can bet I had my glasses practically glued to my head since I was sighting down the beams.

Ok first of all lose the attitude. That's a real good way to NOT get help around here. Now that that's out of the way, Welcome to LPF! :beer:


The whole point of my "plug" was that while photographing just a beam shot of 3 lasers, the most powerful being slightly more than half the power of the one you're getting, is like I did you need to take serious precautions. If you've never had a class IV (or even IIIb) laser it can cause permanent damage up to including blindness literally in the blink of an eye. which is why I said trying to fluoresce material with a 445 is incredibly stupid and a good way to ruin your eyesight.


That now said no, I don't have any experience with those materials. If you want to play with fluorescent materials I would still suggest getting something in the 50-75mw range. There are several ebay sellers who sell "5mw" 405nm lasers that are actually closer to 50 for only a few bucks. You could also build one with either a PH-802T or 805T diode. You could go up to a 6x diode if you want to push it a but higher towards the 200mw range but that's squarely in my "glasses required" range. There are many examples of both types (including my builds ;)) and discussions about the ebay pens in the blue-ray/violet forum. I've used my 45mw pen around around the house trying to see what fluoresces and it works nicely. You may need something a bit more powerful to make some things fluoresce brightly. If you can find it there was an episode of "Best Places to Find Cash and Treasures" that had was about fluorescent minerals that was pretty cool. It could give you some ideas of what to look for.

Good luck and post pics of anything cool you find!

I also won't want to do so without glasses. instead of safety reminders, lets just past that and stick to the topic would be appreciated.

Dude if you dont want your retina's burned out U need a low power 5 mW 405.:wave::wave:

Not necessarily 5mw. I put together a 100mw momentary switch PHR 805 (And Kernel, it's 803T btw, not to get on your case :) ) And that is alright for playing with my posterboard with GITD paint, but the paint is somewhat thin aswell, but it works for my desires :p.

Nooby, stop being a dick. As a member of our community; respect our rules. Safety is practically a rule around here. Do you mind showing us your glasses? I'm beginning to believe you're just being arrogant because you've never owned a 1w+ laser.

We have. We know the power. We know the dangers. Do you?

Heh whoops. How'd I miss that one? I proof read that post at least three times before posting. At least I got it right in my sig. I've used it many times too to make stuff glow since it has a clicky switch.

I too get the feeling this s/he has never had a high powered laser and doesn't know the proper respect for them which is why I posted what I did. I just hope his/her vision isn't ruined because of it. Oh well I'm done with this thread now.

Though the 445nm lasers are damn bright, you'll only fully get to appreciate just how bright (even if just for a moment) when they cause fluorescence. 405nm is even more impressive/dangerous.
