445nm Goggles

Re: Goggles for 445nm

I knew it. So 30 seconds and still no hole right?

Now, do you all believe these holded for 1 min my 200mW lasers?
 





Re: Goggles for 445nm

Okay, I just tested my FP 7$ glasses, and put them in front of my 300mW laser, EF, tested it with an IR filter to be at 215mW so there was 215mW of laser light being absorbed by the glasses. I tested for 1 minute, I don't have a LPM, but I can tell you, not once the whole time did I see a speck of green light on the other side. It melted a crater into the glasses but nothing got through. These are damn good glasses! Don't know about 1 Watt but should be close to being sufficient.

Re: Goggles for 445nm

It's hard to tell. Most of those who already have those diodes are going to be using the higher end products. Once I finish my LPM, I'll be testing out Glenn's BR goggles. The best thing to do is keep searching ebay for the certified products. I wish Frothy were still here, he would know where to get the best of the best.

Re: Goggles for 445nm

I did another test and ran it for 10 minutes and still nothing got through. when I held a paper close to the laser I did see a VERY small amount of green but it was dimmer then the IR I saw around it, barely noticeable, I`d say alot less than 1mW. It was a black peice of paper and I only glanced at it several times so as to minimize exposure to the IR.
 
Re: Goggles that come with the Spyder III good enough?

Thats pretty scary.. I can't see the company sending out goggles that wont work, but who knows? Just to clarify things, you can't view this thing at all without glasses... right? Or can you view it from a distance without glasses?

I'll clarify this. You need goggles for viewing the spot at close range or if there's any possibility of a reflection back at your eyes. Just looking at the beam in the air is fine. Just make sure you look out for airplanes in the sky before firing the thing up and don't point it at anything nearby on the ground.
 
Re: Goggles for 445nm

I knew since the moment I received them that this goggles were the same ones being sold at higher prices everywhere else, just that noone has certified their efficiency.

10 minutes? that's even more than I'd have expected lol
 
Re: Goggles that come with the Spyder III good enough?

Thank you for the clarification! That helps me quite a bit. I still have about a month of research to do before I use this badboy!
 
Re: Goggles for 445nm

I bet they would last an hour, very good glasses. Now we just need glasses for other colors this good and cheap!

I'm not sure how they will last at 1W however, because I noticed at about 2mins, the reflection of the melting plastic stopped. I don't think ~200mW will get through these glasses, but at 1W I think it would just punch through, how long will it take? No idea, but they should be sufficient.
 
Re: Goggles for 445nm

Here was some cruddy testing on my Eagles pair (200-540nm) OD4+...The issue with these goggles, is the lens glows. Even on my 200mw green, it glows the lens...Other than that, I dont see anything passing...Not saying these are safe, but the amount of orange is still decent!!!

If you want I'll redo the test with a lumen meter, to see how bright the orange is...

(Laser is set to 520mA) - I did it at the corner because as expected it was slowly burning them...This was focus to long distance...But i redid the test to find the same results with it focused. I did see a small dot passing through when i focused it. The brightness of the dot compared to the glasses glow was extremely dull. I could hardly even see the dot. Way darker than a .1mw laser by far...So...Maybe these goggles can be tested by others to get more results!
The faded dot wont even show on my camera its so dull...

Results of laser set to focus at 10ft



If your wondering, "So if your glasses are there...Whats on your head?" Thinking stupidly, yet clever, I put a paper cone to my camera. In short, My eyes was the cameras eyes :) This way no light got to me, but the cameras LCD

Why not just buy some glasses from Frothy himself? OEM Laser Systems is his store, they sell a wide range of fully-certified laser goggles. Some people in the Groupbuy section are talking about getting a buy together for glasses from him, if they get 25 orders together, he'll knock 20% off his website's price (smaller discounts for smaller quantities, as well).

Funny you mention him here though, because I believe threads like this one were a big part of why he left and stopped posting here.
 
Re: Goggles that come with the Spyder III good enough?

Now they don't even offer the upgrade to better goggles on there website, you can just add a pair of cheap ones for $29.99... either I got ripped off or something sketchy is going on!
 
Re: Goggles that come with the Spyder III good enough?

I had a convo with Tracy from WL... this is what he said....

Tracy: Welcome to WickedLasers! How can I help you?
you: Hi I'm wondering about the OD rating of the arctic laser glasses
you: do you know what the OD rating for 445nm is?
Tracy: The required Optical Density for laser safety eyewear for a 1W 445nm laser is 3+ for accidental exposures of a quarter of a second. However, an O.D. of 4.4+ is required for longer exposures
Tracy: please click this link for more informations: http://www.wickedlasers.com/laser-te...ht_hazard.html
you: yes.. i know that
you: what is the actual OD rating of the additional glasses that you include with the arctic
Tracy: the actually OD for the free lasershades is 4.4+
you: OD 4.4+ for 445nm correct?
Tracy: yes
you: ok thank you

Hope that helps! -Adrian
 
Re: Goggles for 445nm

I hate it because I know things were gonna turn out this way.

Things go like this:

1.-You buy a cheap goggles and do not expect much from them, but since everyone says they work great...
2.-You test them and they work amazingly good, much better than you would have ever expected for 405nm and 532!
3.-You ask people in the forum: hey, are these working that good for 445nm too?
4.-Someone answers: "wow, I tested them and they work like a charm!"
5.-Someone come and says: "you, bunch of irresponsible people, buy certified goggles and shut up!"

why shouldn't I use this goggles if they just work. Because whoever that certificates the goggles wasn't paid for testing this model? Honestly, as long as they protect me, I don't care if there's a "certified goggles" sticker on them or not...

And before you answer: "only certified goggles are reliable because they test them with the proper protocols...", listen to this. A member tested them against the diode for 1 minute and they did their work. Certified goggles do only certify that you will be protected for 10 seconds. If that's not enough for you, well, I'm sorry, it is for me.
