405nm is just barely outside the UV spectrum. Also, I agree that a 1mm-2mm spot would be alot less efficient when it comes to DNA scrambling than a broad coverage bulb. As for lasers as a component in a survival kit... Well, I guess you could always try to visually signal to others with morse...

Germicidal activity in light peaks at the 260nm-280nm range. Maybe a 262nm UV laser? Do they make 5mw portables in the 262nm wavelength? :thinking: (Excuse my ignorance I'm new to lasers, but not UV.)

Thanks again everyone. Also, Meatball excuse my ignorance on the matter, but are there any diodes in the UVC range? I have worked with lower powers of 280nm light, and I am aware of the risks while working with these. The two lamps I have owned had a visible light filter retrofitted onto them so...

That's a very sobering article, thanks for linking it. One thing it does stress is the importance of following safety practices to the tee at all times. With some peoples luck, the one time somebody doesn't want to put on their goggles is the last time . :lasergun:

Thanks for this. I might order a couple of goggles for different wavelengths to get me started on my new hobby! Also, for those buying an Arctic, would the 10mw power of the laser's beam through OD2 goggles raise the MPE to a point where the blink reflex could save your vision?

Sorry about that, not too much fun. Those troopers are everywhere down here because of all the things that filter up into Florida from Cuba. Small town police forces are incredibly strict too! Thanks for the welcomes everyone!

I have heard of this website, but there were a few complaints here in the U.S. about customs seizing lasers. Do those reports hold any merit? Also, what is quality of these lasers? ( I'm just starting out so top of the line products aren't necessary as long as they still have safety features.)...

Hello Everyone! I just thought that I would post a quick bit about myself here so that you can see where I'm coming from. First and foremost, I would like to bring my age to the front of the table. I don't like lying, so I will come right out and say that I am sixteen. I hope you can give me...
