Nope. Well, surely not the first ones they sent out (light orange + not enough protection). I think the second style they were sending are slightly better.
Personally, I use these for 445nm, 532nm, and 1064 (IR):
Multiple Wavelength

If you're asking whether those goggles live up to their stated specification, I have no idea. They're not certified as far as I know.

Glenn,

I've been using the 405nm yellow lensed goggles you were selling. They work way better than the red lensed goggles you also had for a limited time. With red goggles I can still barely see the beam of my 445nm being pumped with just a smidge above 1A. With the yellow goggles, I can only see the fluorescense of the surface it is shining on, and a faint "halo" of 445nm light, so faint that I can't be positive that it's always there.

Just sharing my experiences. Thanks!

Default Re: Eyewear

I wanted to share a site I found after doing some looking around online to answer questions I wasn't able to clear up on LPF. After reading a post from Bluefan I found myself armed with the jargon to find my answers:
Quote:
For visible green, the alignment goggles usually are OD2 for up to 100mW, and OD3 up to 1W. Please note that goggles need to be certified according to EN208 to guarantee that this OD is sustained at least 10 seconds during a direct hit. EN207 is for complete protection and is more complex.
Anyways, here is the site: NoIR Laser

They have the most comprehensive collection of high OD rated AND CE certified laser protective lenses that I've seen in one place online. In addition, they provide performance graphs for every single product. As if that wasn't enough already, there are great articles describing what the technical specs jargon actually means and translates to in terms of usage. There are other neat safety concepts explained under their "Laser Safety" section too.

Overall the prices can be quite high and there might be better deals out there for certain models, but I think the sheer scope and range of certified protective glasses is worth bookmarking the site for. I also thought this might be some good information since it finally explained to me what VLT was in a way that I understood.

I hope this helps contribute.


EDIT: I believe this is the source from which OEM gets their glasses. Anyone know for sure?

I don't think you're supposed to be seeing the beam at all with any real protection...

I was wondering about blublockers, has anyone measured the OD on those? I heard a few LPF peeps use them for 445.

urgggh... ima just buy the wicked laser artic one i guess

im not willing to pay for goggles that cost more than building my laser =[ (yes i know at the cost of my eye)

are the arctic goggles worth it? or is there something that is cheaper or in the same price range that is better

cause im just assuming if the wicked lasers were meant to protect from a arctic, then it can't be all that bad

Default Re: Eyewear

The glasses that came with my Arctic are fantastic for the 445nm light. There is no dot through them, only a diffuse orange glow from the lens material fluorescing (I'm assuming). This is also with the standard lens attached with the laser on full power. There are some melted parts on the side of my lens from me testing it out, melted not charred as you would probably see if there was only a thin coating that was burning off.

There were a lot of problems with the earlier glasses, from what I've seen on other posts here, but I think WL solved that problem.

Some things to consider:

1) Makes sure you buy their glasses FOR the Arctic and not just blue light lasers. I don't know if they consider the two separate but they might and you could not get what you are expecting.

2) I don't believe WL glasses are EN207/EN208 certified.

3) I have no idea what the OD rating is for my glasses and I haven't measured the power with an LPM either. My judgement is just based off of what I'm seeing through general observations.

4) If you really wanted to feel the safest I would buy only certified OD 7+ glasses. Like you said though this will be pricey. Personally, I will be spending the money for such a thing even though I feel confident my WL glasses will protect me from an accidental reflection. My line of work depends greatly on me being able to detect varying shades of color and minute details through a microscope. So my eyesight is critical to me and I'd rather have above and beyond protection.

yeah and i understand what you mean by your eyesight and how important it is to you

just i want something thats reasonably priced that will do the job, im not gonna be intense burning with the laser, most im gonna do is prolly just observe the beam it makes when shooting it outdoors
