445nm Goggles

Yeah, well, but believe it or not, those hold 200mW of 405nm and 200mW of 532nm for one minute without melting. And yes, they are 7$ LoL

That´s not true.

I have two of the o-like goggles (there are two sorts of this cheap goggles around which look the same) and my 185mW greenie melt both of them in less then 8 seconds.

Edit: + bump on this one
 





Re: Goggles for 445nm

Yeah but how long till they bleach? I would think the protection would be long gone before it started to melt.
 
Re: Goggles for 445nm

"melting" means making a hole on them. I also made the tests with the beam focused to the infinity. Obviously, if you focus it on the goggles, they won't last much XD
 
Does anybody else find it disconcerting that WL doesn't list 445nm goggles on their goggles page? Surely the goggles they ship with the Spider III will provide protection. I can't even imagine the legal troubles they will get into if their goggles only provide a false sense of safety.

Wicked Lasers OEM Goggles
 
The goggles sold with it cover everything from violet up to green. Likewise, their green goggles will cover blue and violet too. It would be nice to see this explicitly explained, and/or in an OD graph, though.
 
Well if you look at "Green 532nm LaserShields Goggles", the graph of the OD rating shows 2+ at 400nm to 532nm. Therefore, the green blocking seems to be have a simliar OD against 445nm lasers. Judging by the graph provided, ~450nm seems to have a ~3+ rating.

Of course, I do not know if LaserShields have the same optical density as LaserShades since LaserShades does not have a provided graph. I would assume that they'd provide protection since (many) 532nm blocking goggles seem to block out the range of 400nm to 532nm (graphs provided from other goggles).
However, I don't have their LaserShades graph, but they should provide some degree of protection. :)
 
It's mostlikely the same goggles for 532nm (the red goggles) for those have been confirmed to also block bluray.
Also, RED is the "opposite" color for both green and blue. So it only makes sense that the red goggles would absorb it :p
That's what I think is going on anyway :p

edit: oh dear it looks like I was beat several times while typing my post :p lol
 
Re: Goggles for 445nm

Ok had the laserbee running and put the glasses in the beam.

Thay surprisingly let less than 5mW threw. (from how bright the dot looked in my first post)
But after 15 sec's thay noticeably started to deform(small spot), after 35 sec's it stared to smoke(larger spot). I did not test any further.

Goggles that come with the Spyder III good enough?

I just purchased the spyder III, and it is my 1st really powerful laser. I intend to take every safety precaution possible while using it, first and foremost being my eyesight. I upgraded for $60 to there better goggles. Will those goggles be good enough? Also, will this laser hurt others eyes if they see the beam from a distance, say at least 50 yards? My dad and brother will want to see it, so I assume its not safe for them to watch me use it.... I have lots of research to do before I actually use this thing, any safety tips would be greatly appreciated.
 
Re: Goggles that come with the Spyder III good enough?

No one knows if the goggles will be good enough, no one has gotten their Arctic to find out.
 
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?
 
Re: Goggles that come with the Spyder III good enough?

I would start with this thread: http://laserpointerforums.com/f65/so-glasses-shipping-wicked-arctic-effective-51653.html

What I posted in that thread:

Everyone inexperienced will receive these glasses and assume they are safe for use with this laser, but I have yet to see a single OD or wavelength rating, or a single statement of certification for effectiveness. No ANSI standards, no OD, nothing. Just "safety glasses".

Personally, I trust certified safety goggles. An ANSI standard, designed by experts and recognized by all laser professionals, exists for laser safety goggles. There are also other standards out there in addition to the ANSI standard. But either way, without any kind of certification, how do you know what you're getting or how safe it will be? But in the end, it's up to you.

Thanks for the link! Can you recommend a decent pair of goggles? The upgraded ones on there website are from NoIR LaserShields, and the graphs are located here: Green 532nm LaserShields Goggles

Here is the link to the manufactures website and there certificates are on that page: NoIR LaserShields: Laser safety goggles for green 532nm OD 3+ laser alignment applications. Laser safety glasses for Argon and KTP.

Are they good based on whats on the manufactures website?

Well, we're trying to get a group buy going in the group buy forum. If we can get 25 goggles, they'll take 20% off and give us free shipping to the distributing member. Pretty darn good deal. The goggles are roughly $70 each.
