Default Re: A Plea for EYE Safety!!

I didn't mean to say that goggles were perfect, if that comment was directed at me. Of course they aren't, and I was only saying that they should have to do that to even purchase the diode. Unfortunately, with almost all dangerous devices, it's always up to the end user to be safe and responsible with the device, be it a heavy machine or a 1W laser, they're both incredibly dangerous, and failsafes can be implemented, and always should be, but alas, no system is perfect.

Default Re: A Plea for EYE Safety!!

I suppose the best thing to do here is give advise on goggles that will provide good protection against 445 nm. As this wavelength is pretty new, there might be a problem with that. Goggles protecting against 532 green or 405 violet are available, and tested, but we have very little evidence on which goggles protect well against 445 nm.

I would assume that many low-pass goggles intended for protection against 532 and 405 would work fine with 445, but that assumption is by no means a guarantee. If you are concerned with safety, its paramount to offer a solution for protection - which probably boils down to some people here testing various kinds of protective eyewear for 445 nm.

Here you go:

ARG - UV, Blu Ray, Argon, Blue, KTP Green Protection ARG - UV, Blu Ray, Argon, Blue, KTP Green Protection [NR-ARG-EN207] - $78.20



This is just one example, they have several models that would protect against 445nm.

All the safety testing has already been done by real professionals, no need to reinvent the wheel.

At OD8 could you even see the laser AT ALL? lol that could be dangerous in itself

Thanks for posting here.

I would hate to see flame wars in this thread. So please (and I'm not directing this at any particular person). If you have something you want to say, say it respectfully and remember, its better to be over cautious then then under cautious.(Just My Humble Opinion)

Default Re: A Plea for EYE Safety!!

I'm glad I've seen this thread. Not because I'm not protected eye-wise but I worry for the future. The title of the thread I was thinking of was, "With great power comes great responsibility".

I was going to suggest a measured response to sales too. Thank you Steve, (LSRFAQ), for putting things in far better words than I ever could. How many posts here have demonstrated that some of the general, (largely ignorant), public can not be responsible with a laser? 50mW, 100mW, 250mW.... Whatever the power there is always someone in trouble for it. The genie is out of the bottle with these oh so cheap diodes and as part of this forum I would like to see self imposed restriction on sales. Yes, ebay are going to be offering these, (in a week, two weeks?), but I for one give a pledge right now not to supply a third party with one of these without some sort of framework of decent checks. Heck, I might even limit myself totally to, "consumer". I sold a 20mW argon last week, and still kept banging on about safety, but for the same money it could have been 1/2 a watt! Not from me it won't!

I'm excited about MY new purchases and excited for all the folks here and elsewhere that know and respect the science but I wonder how long it will be before the, (UK), authorities have an issue and I don't look forward to the first news report.

I think there will be repercussions from these diodes and soon. Please be responsible.

Default Re: A Plea for EYE Safety!!

I totally agree as well about the saftey aspect, however those of us that know how to handle these class IV diodes/lasers responsibly shouldnt have to suffer for those that dont. This is changing history for us, and im thrilled to be a part of it. I also totally agree there should be certain restrictions, however we have been given a golden opportunity, calling casio *could* potentialy ruin this for those that are responsible.
Reading this thread actually killed some of my high hopes for these wonderfull diodes and new technology emerging, we have been playing with 12X class IV's for a while now without 'detrimental' problems, I dont see why it should be much different now(except the price).
With everything LSRFAQ said, I will be saving up to stock up on these blessings of science, before it is made so we cant get them anymore, or for this price. Seriously though, if this becomes a problem, and these diodes get 'changed' to something not so user friendly to us hobbyists, IMO that would be a loss.

Which is why you need the ANSI specs, as Steve pointed out. ANSI specs lay out exactly how long the goggles should protect for a given exposure. While Dragon Lasers say their goggles "exceed US standards", how far can you trust that when they don't even publish the name of the standard, as OEM does on their site?

Just because the diodes can handle 1w, there is no real reason to drive them that high.

Personally, the diodes I ordered will probably be operated in the 200-300mw range. I didn't get them for the power, I ordered them for the wavelength.

With OD8 goggles you wouldn't see the beam, but the spot would be visible. a 50mw green beam disappears around OD3, but the spot will be visible.

Default Re: A Plea for EYE Safety!!

I completely agree....

But I just have two things to say.....


1. Not everyone will be driving these that high. I ordered one and I am going to have mine around 400-450mW. With that said, I realize that 400mW is still very dangerous.

2. Not everybody will use these lasers in really dangerous situations.
I don't plan on using my laser to burn stuff or point around the house where I can get a reflection. I plan on using mine outside only, and just for pointing purposes. Pointing at stars and pointing at far out trees.


I agree that we should really be watching our safety with these. But just because somebody doesn't have a high post count, does not mean that they should not be allowed to order a diode. A low post count does not mean that you are incapable of correct safety procedures. And a high post count does not mean that the person will automatically be really safe.

Default Re: A Plea for EYE Safety!!

Same here. My signature won't have as much street cred but i'm driving mine at 450ma. Looks like this should do 250-300mW or so. There's just no reason, to me, to have a watt in a handheld.

Default Re: A Plea for EYE Safety!!

the common noob wont buy a projector, too much money. The more advanced noob that knows how to aquire and power the diode, will also have saftey knowledge. The only ppl that will run these that high are members here that want to test or push the diode and are qualified with the saftey aspect. As long as no one builds a 400+mW laser for a 'noob', our hobby should be safe....

EDIT: Even I have no real use for anything near 1W, I will run mine at 600mA, whatever I get out of it is what I get, I as well am after the color, but the power is a perk if you can handle it.
