When burning, the dot itself, where the material is burning up, can be quite bright.

If what you're describing is seeing an after image, (just as you would from looking at anything else that is bright, say a lightbulb), the effect would be basically the same with the eagle pair goggles.

As always, I suggest if you are worried, get your eyes checked out, and get yourself certified goggles.

Yes this is exactly what I'm talking about. If you take the shade off a lamp and look at the bulb for a minute you then have an afterglow in your vision for a few minutes. I just was curious if eagle pair had the same thing occur.

Yes I'm using the right pair, I got them from the link in the first post, they have the SCT orange. The beam itself is invisible with these on and I can clearly see the shape of the dot at any distance for focusing without interference from fluorescing, its mainly just when I focus in on something and stare at the dot while it burns.

Then no, an eagle pair wouldn't change that. What you are seeing is other wavelengths being emitted by what you are super heating with the laser and there is nothing you can do to block that short of blocking the whole visible spectrum. The best way to solve that issue is not staring at it too closely. Otherwise its no more damaging to your eyes than a regular bright light. A headache can also sometimes be an indicator that your goggles are insufficient.

However as Infinitus said, if you are worried, certified goggles are never a bad idea.

Heads up!

I just got 3 pairs of the Uvex S1933X from eBay. These do not effectively block the 532nm wavelength. However, it does block 445nm and 405nm.

Once I finish building my TEC based LPM, I might sacrifice one to test it how well it blocks those wavelengths.

It will be a while though. The module I got from Israel is taking forever to get here.

When did you buy it? My girlfriend bought something from Israel and it took her about a month to get it!

I purchased a pair, and have tested them with the 532nm wavelength and they worked great. (Link in signature for review)

Now, note, the ones I ordered are the ones mentioned in the original post "S0360X", not the "S1933X" tested above. There's also the possibility that they changed the dyes for both models, and what I ordered is actually an OLD pair, before they changed the dyes, and therefore it will still block the 532nm wavelength like it used to. Either way, there's a link to the seller in my review, and he has over 130 in stock, so if they are the old ones, there you go. :beer:

I actually got mine from the same seller but these do not block green. It's the S1933X model. I'll have to grab a few pair of these.

There is another test using the S1993X and it performed the same with the S0360X on 405nm to 532nm.

I purchased a pair of these and also found that they weren't working very well for 532nm wavelength. When I pointed my "5mw" 532nm ebay pen through the lens, you could still see a small green dot. It blocked out some, but not all. They work excellently with my 3W 445nm though! Note: I bought the one from the original post, the "S0360X".

With green and red lasers especially, I find them nearly impossible to go on appearance alone, to judge whether goggles work or not. Even .1mW of green appears BRIGHT.

Personally, I consider these goggles, the S0360X, to be secondary, to simply properly setting up the lasers in the first place, and how I handle them.

If you want to be on the safer side, I highly recommend eagle pair, or certified goggles.

It's interesting, because I bought a cheap pair and just a faint blue patch that can only be seen in the dark will come through them. That's from my 1.5 watt 445nm. Burned a spot in them, of course.

Your eyesight is worth the price of quality certified laser safety glasses that attenuate the wavelength you are working with, be aware that the range listed may give more protection at the center of the listed range than the limits, so take time to look at the graph that shows the OD+ across the listed protection range.
