proof of concept: cheap laser protection + pics

Re: proof of concept: cheap laser protection + pic

Acrylic is too fragile. Real laser protective glasses use polycarbonate or dielectric glass. I know you are trying to build a better mousetrap but you are potentially opening yourself to litigation if you try to sell a homebuilt protective lens or let your friends or family use them and someone is injured. That is why protective lenses must be FDA certified in the U.S. and CE certified in Europe.

If you are just experimenting, well that's your business. But if you provide your lenses to anyone and expose them to laser light, you can't say you haven't been warned of the consequences.
 





Re: proof of concept: cheap laser protection + pic

cheers for the advice- will heed warnings :)

one more idea i want to bounce past you first before abandoning this idea:

several layers of this 3d goggles filter layered between 2 sheets of glass?
 
Re: proof of concept: cheap laser protection + pic

Aren't most wavelengths opaque to glass?
 
Re: proof of concept: cheap laser protection + pic

All the power would still go through the glass so it would still end up melting, get some real lasers goggles...

...lazer... ;D ;D ;D

He already has goggles, he's just doing this as an experiment.

thank you :) at least someone understands :-/

I hopefully have another pair coming too...
 
Re: proof of concept: cheap laser protection + pic

So which ones did you order this time? The sport ones, or the nerdy ones?
 
Re: proof of concept: cheap laser protection + pic

I can't see why them 3d goggles using the red plastic side wouldnt work. Sure if you stood there for 3 minutes shining a laser in your eye, then i think you deserve to be blind, but really the laser goggles are just to protect your from direct exposure. After all, it's better than nothing!! I can't see why acrylic wouldnt work, yes it is kinda fragile, but who's gonna be throwing their goggles around the room anyway ;D If you are sriously into lasers, and think you will be for a while, deffinately get some goggles, but if you are the kind of person that just mucks around with them in your own home by yourself, and changes hobbies alot, something like this would work.

Oh yeah, I forgot you ordered those. :P I'm guessing those are good good for blue, green, and IR lasers no more than 500mW.

the prob I have is that CC has tested them and they have an OD of 2 for blue and green an OD of 1 for red but an estimated guess of OD for the IR... he is trusting the label which im not sure is the right thign to do...

I want it for leaky IR greens which can output 100mW IR so an OD of 2 would be good....
