I have these goggles DBY - YAG and Harmonics [NR-DBY-EN207] - $157.50... are expensive but they can be used against 445 nm, violet, green and YAG (1064 nm) with a protection of OD>7

Thus reducing the beam to 0.00012mW? Isn't that overkill? Then you can't see what you're pointing it at, and you end up cooking something without intending to.

I use them only indoors and in any case the dot is always visible due to emitted fluorescence

BTW I have also a 10KW pulsed YAG

Ouch to a couple of those, I'm fully aware of how dangerous these lasers can be and admittedly may be a little naive when it comes to things of this nature but my goal if any was to check up with people who have been there. To be fair though I went out of my way to get those lenses because they are designed specifically filter blue light and they are quite dark. So I "assumed" they would be fine. I've seen other goggles and glasses made just for that wavelength and they appeared to be orange or reddish lens to block the opposite side of the spectrum. I would be willing to bet thats all some of these are, just a regular dark orange lens. Anyway I'm sure this will be picked apart as well but I suppose that comes with the territory of being a filthy stinkin NOOB!!! Thanks for the constructive criticism as always.

As everyone else says, before you even start this hobby you have to learn how dangerous lasers are....

you cant cut corners with this hobby....

Does the polarized goggles block lasers better if the polarization axis is matched ?

Im all for laser safety, believe me. But one thing that really bugs me about this forum regarding safety is :horse:

I think he gets the picture, pretty soon its only annoying to hear the same thing from a dozen people.

You've proved your point, If he cares about his eyes and the longevity of this hobby like most of us do, he will get some glasses.

Could be a troll too. Some people have nothing better to do.

Like me. :eg:

Whatever happened to that "troll overlord" title? now it says "class 4 laser".

I had my account closed for personal reasons, when he reactivated it the text was back to normal. I just never asked to have it put back.

Ah okay, cheers.

btw i wonder if s2kkid stands for s2000, aka honda, the f20c engine is wonderful

f22 sucks ass however

O-Like 1.2W vs Sunglasses Clip

So I read the original post, and had a strong desire to slap someone for stupidity. Since that's not an option, I did the next best thing.

Used the 1.2W O-like laser to see what it would to do some scratched up clip ons I'm never gonna use again.

The result is attached. The picture is not edited except resizing.

Basically passed beam over the lens three times, over a total of ~6 seconds.

Just imagine what it would do to eyes.

I have Black Iridium Len's on my oakley thumps...the beam passes through them full power(spartan 1w).

And let's not talk about how they faired against 2 watts...lol

Do the goggles protect against flourescence? Let's say you pointed it at a bottle of orange flourescent dye diluted with water, isn't that a different wavelength and therefore one you're not protected against?

Also... does that mean you could see the dot of a 0.0001mW 445 flourescing stuff?

The color of the fluorescence is not coherent. I suppose the brightness could cause a temporary bleach of the cones in your eyes, but I've blasted all kinds of fluorescent item with my 1.1W 445nm laser, and brightness has never been a problem with my goggles on.

true, and usually it's not even a specific wavelength and then visible through the glasses
