Welding glasses for red laser?

[saintje]

Hi,

I've got a 200mW red laser, but after playing a couple of minutes with it, I noticed the spot is really way too bright to look at for longer times.

I've searched for protection goggles, but safety goggles for red lasers are very pricy. I did find some welding glasses that are fairly cheap and was wondering of this will do. These will probably don't do any good when I shine the laser direct in my eyes, but this can be avoided by handling the laser very carefully.

So will these welding glasses be good enough to filter the brightness of the dot? Or is it maybe too dark to see anything else?

Thanks.

I only saw the google custom search and that kind of searching s*cks.
I see the normal search now so will do a search. Sorry.

Your lasers wavelength is 650nm. Go to the "Companies" section and search through the Chinese retailers for cheap 650mn goggles.

Welding glasses do nothing for lasers and can hurt you more because they open your pupil, and expose it to more light.

Good luck.

Thanks for your advice.
But in the meantime I've found a seller on ebay that had goggles for 635-670nm (my laser is 660nm according to it's sticker) for 15$ (+10$) shipping.

Thats a decent price. You might find some cheaper one from the Chinese, but they could take a month to arrive.

 

[saintje]

Yeah, And I couldn't find a cheaper one on the sites I know, and also not on ebay.
Don't know how long it will take for this one to ship, but I will see.
It has an OD of 1.3 @650nm, that according to the seller let's 5% of the light through.
That would make my 200mW a 10mW red, and that's good enough for me to look at.

Even though you are buying these glasses....10mW is still potentually unsafe if it is shined directly into your eye.

FDA states that anything above 5mW can potentually blind you.

I know, I'll just resist the urge to shine in my eye
Heheh, yeah, I know, an accident can always happen, but it's like handling a gun, always keep your head focussed on safety, and don't do anything stupid.

Wanted to update my thread.
I just received my safetyglasses, en they really do their job.
And I think my laser is underpower, or these glasses are underrated, because I can't see the spot at all anymore.
It doesn't let any of the beam through, so it's protects your eyes

as long as you don't get direct hits so usually, cheap googles will work Ok. Just don't feel safer because you are wearing them and start doing things you wouldn't without them

I'd be concerned if 10mw could enter my eye. 10mw can do damage in an accident! that's why it are accident... Cheap goggles can work for 200mw, altough not that much higher because the goggles may melt and lower in OD. I'd get something OD 2 at least.
But 1.3 is 20x better than nothing, that's for sure.
