190-540nm Eagle pair glasses review

[Foshizzle45]

I'd like to start off saying first, that Gary (the owner) Is very good with customer support, he was able to answer all my questions within just a few hours.

Now to the glasses, They came in a packaging that stated USPS FIRST CLASS MAIL. It only took 4 days to get to me! Inside the box was the glasses case. Inside the glasses case was a cleaning cloth and the glasses. The glasses are comfortable too, and they are quite easy to see through as well.

The glasses state 190nm-540nm OD4+. So I decided to test it out myself(I don't have a laserbee, I have the old fashioned way, you know, My own eyes..) I took my 5mw shined it at it, and to my liking nothing came through, now i tested with my 10mw, and then i saw a small dot! In the picture it looks purple, but it looked green in my eyes. (If you look closely, the small dot is on the grey part of the computer screen). I think I may have gotten a de-faulty pair, or maybe it's not OD4+ for 532nm. I have seen review's with 445nm on the glasses, and it has blocked 1w+. Sorry for the bad picture quality, it was taken with my phone.

P.s, sorry for this being a bit sloppy of a review, it was my first one, so be easy on the critisism if you have any

ALSO! I have no intention of using this to put down the company, Gary said he would be happy to replace them, so I'm quite happy to hear that. Survival laser's is defiantly in my top 3 laser company's as of now.

I've seen unstable greenies sometimes leak through the my pair— I'm not quite sure what's up with them...

On another note, I just ordered the EP-1 Black... I'll see how those do when I get them (ordered at a large discount from a retailer in China).

Good luck with them.. I am not sure if I should just hold off on sending them back, and just keep them for my 1watt, One thing that the Eagle Pair is great for, is looking at the dot, I can barely see it through the glasses!

With my cheap greenies, I can't see the beam or dot at all when they are outputting 532nm correctly— if you can see the dot from your greenies, then either the laser or the goggles are messed up.

For the 1.2W SL I, it works very well, and I'm seeing the dot reduced to a few milliwatts.

:/ I hope I didn't get a bad pair... This is sorta bumming me out now.

Does anyone know how to go about returning something to survivallasers? Like do i send it back in the same box that they sent it to me with?

 

[bennett326]

have you contacted them or pmd Garoq

have you contacted them or pmd Garoq

Yeah, I shot him an email about an hour ago, but he probably won't reply till tomorrow afternoon, so it would be easier if i could send it out before the truck comes to pick it up. So i was wondering what i could do, if anyone has any experience with returns.

The protection level of these goggles has a sharp cut-off above 540nm, so it may be that some of your green laser's output wavelength is closer to the cutoff than actually 532nm. I seriously doubt there is something wrong with the goggles. See the wavelength vs. OD level here.

If you want goggles for use with DPSS green lasers then you should be using this model:

Eagle Pair® 190-540nm & 900-1700nm Laser Safety Goggles

They cover 532nm and any 1064nm infrared leakage. The goggles you have block virtually no 1064nm light.

Your right, I regret not getting those, Is there a way i could trade off and add the extra few bucks on paypal? Or something around those lines?(Not to be a pain in the you know what)

^^^Working this out via email and/or PM.

DPSS greenies leak 808nm also, which those don't protect against... Just throwing that out there...

 

[lovellaser]

or you could just install IR filter or in the future, buy IR filtered lasers

I've read conflicting information on this. For example in this paper, Sam Goldwasser only mentions the 1064nm component. Other sources I've read imply that the ratios of the two wavelengths vary with the drive current. Are you aware of any other references that include measurements of the amount of IR leakage from typical DPSS greens at the two wavelengths?

It may be interesting to note here that the infrared leakage is mainly 808nm, not 1064nm. The 1064nm is reflected back into the Nd:YVO4 by the output coupler, however, the output coupler is not coated for 808nm, and this radiation passes through unhindered. As a result, the majority of IR laser radiation leaking from cheap laser pointers and modules is 808nm, not 1064nm. The only time 1064nm will leak out is if the coatings on the output coupler are damaged.

I read that, and it's anecdotal. I'd really like to see some actual test data.
