Lasers that use AAA as opposed to others?

[Sigurthr]

Gotcha. Aye thanks indeed for the update, I hadn't realized they changed management. I likely would have ordered again from them still thinking it was the old bunch!

This is a real shame, as I was planning on getting my CO2 tube and PSU from them. I don't really know where else to get it from that is reliable. Their price is still the lowest I've seen at $340 shipped for both tube and matching PSU.

There is a reason why its the lowest price. :beer:

why dont we ever offer advice and safety advice simultaneously? its too easy to say BUY GOGGLES!

Amen brother.

Holy crap, now I'm scared. So do you have any good goggles I could get too? Sorry I'm very new to lasers, I've only had the ones that you could get from any store (they were probably less that 1mw). If anyone could recommend me a good 250-300mw laser and some goggles that would be awesome, thanks.

I'm going to grab a couple of cheap links for you. It would, in theory, be better to buy the more expensive goggles that others recommend, but I think these are good quality laser glasses for a LOW price.

Personally, I think when someone comes on here with a budget of $60 for a laser and we send them a link to $40 goggles, they just aren't going to buy goggles.

With these, I think they might actually get purchased and used. They are less than $9 and shipped free!


Amazon.com: Uvex S1933X Skyper Safety Eyewear, Black Frame, SCT-Orange UV Extreme Anti-Fog Lens: Home Improvement

I was skeptical of these, so I did some digging and found Uvex is made by Honeywell, which is a respectable company.

I also found this PDF file with specs on the SCT-Orange coating... It has a nice graph of the wavelengths, but here is some of the key text...

http://www.uvex.us/uploadedFiles/Uvex_Lens_Tech_Broch(1).pdf

"SCT-Orange offers a wide range of spectral protection. It absorbs >99.9% of potentially harmful UVA and UVB radiation. It further provides protection by completely absorbing visible light up to 540nm, which includes violet, blue and certain green wavelengths of light..."

Of course that includes 532nm greens as well.

Call me crazy, but I would rather a person use their head in dealing with lasers, than rely on cheap goggles which will offer a (possibly) false sense of safety.

If budget is the issue, the person should not be messing around with lasers in the first place.

For the handheld lasers that we're dealing with, up to 2.5W, common sense, and a systematic approach to safety (not shining it around without regard to the termination point) will always do more than ANY goggles.

The goggles you link to are not laser safety goggles. They may or may not work.

Why are you willing to recommend such goggles? Have you tested them out with lasers? Has anyone?

Are you taking responsibility if they turn out not to help and there is eye damage? Are you planning to test the goggles he orders, or every set of goggles that someone buys off of that link?

Here's the last sentence from the pdf link...

As with all personal
protective equipment, it is the
employer’s responsibility to conduct
an on-site or workplace hazard
assessment.

They certainly aren't taking any responsibility upon themselves... nor is there any mention of these being useful specifically with laser light.

Sorry for the rant, but IMO it's better to offer no advise than to offer questionable advice.

I think it is mandatory for a person buying a laser to purchase laser safety goggles.
$50~$60 is quite a small investment as compared to "eye surgery" or you can blind someone and get sued, n eventually you have to donate your own eye to the person for the case withdrawl and so on..
In otherwords, Never ever think of buying a laser if you dont have proper eye safety beforehand..
u can also ask someone to send you some used goggles if u dont have the money for a new. but why spend on a decent laser and not on goggles. they look cool though.. get an eagle pair n be safe. good luck

Come on, that is fantasy! You can say that until you are 445 in the face, but an 18 year-old who wants a laser and wants it now is gonna say, "yeah, I'll get goggles" and then order the highest power laser they can afford or like the host or marketing or whatever and never get glasses. Or maybe get them much later.

But if you steer them towards an inexpensive option, they may actually buy and use those.

The goggles you link to are not laser safety goggles. They may or may not work.

What makes you so sure that the Chinese made eagle pair goggles are legit and that they work?

Eagle Pair English page

They SAY they meet all the standards, but Chinese companies are notorious for fudging the data.

Why are you willing to recommend such goggles? Have you tested them out with lasers? Has anyone?

I have, yes. I have four sets.

On my 1.25W SL I couldn't even get a dot on the other side to measure. With my ~300 mW o-like green, I got about 25 mW which is probably IR. I am waiting on IR filters to test that theory.

Are you taking responsibility if they turn out not to help and there is eye damage? Are you planning to test the goggles he orders, or every set of goggles that someone buys off of that link?

I'll take the same amount of responsibility that Survival or Eagle Pair takes...

Sorry for the rant, but IMO it's better to offer no advise than to offer questionable advice.

I don't think it is questionable advice. The spec sheet is there to read. It blocks over 99% of light for any visible light laser below 540nm. It is an American company that I trust is not cooking the data.

I have conducted my own tests with high powered lasers and an LPM'S and several times I get the same thing.

You do as you like, but if there is a kid in here with $60 to spend on a laser, I might be able to convince him to spend $8 (free shipping even) on a pair of safety goggles whereas he might have just gotten a laser with no goggles when presented with a >$40 a pair option otherwise.
