Error in the text: 1000mW laser with 532nm wavelength which is green light.

1000nm light is infrared.

I know that Xwitter is usually a reliable source, but 1000nm is outside visual range and therefore not green. Green lasers in the ~500nm range will absolutely damage a camera sensor, but you'll need good aim and sustained illumination.

    Also make sure your friends have laser goggles, and that nobody is anywhere downrange if you're trying this. It takes way longer to blind a camera with these than it does to blind a human/animal, and it will turn minor vandalism charges into felonious assault.

    Also worth noting that in a lot of places you'll need a license to legally own and operate a class 4 laser like that Edit: I looked into it some more. This might only be true for commercial facilities. Idk though I'm not a lawyer

    "class 4" is just the highest class, being over 500mw. Technically, the experimental lasers they use on warships are class 4 lasers.

    Most countries don't restrict owning them, but they do restrict selling them. When you have one, it's kinda like owning a kitchen knife, perfectly legal, but as soon as you do dumb shit with it, thats still on you.

    And class 4 lasers make it VERY easy to do dumb shit.

    I don't think a license is going to help you if you're found walking around with a 7 watt laser hooked up to the relevant drive circuitry. They're still going to presume you're up to no good, and, when they find a camera with a burned sensor, they're going to assume it was you. I guess the moral of this is: don't get caught.

    Probably don't even need that much, my cheap eBay laser pointer from 20 years ago damaged one of my first smart phone cameras in a couple seconds because I aimed it directly in. It was red, too, not green. Both work though.

    I didn't want to some in my rites so I thought the camera lens would be OK. It was indeed not OK.

    They ostensibly meant mW rather than "nm wavelength" based on the image, but they might not be the brightest laser in the activist's pocket.

    Edit:

    Jason Bassler is co-founder of The Free Thought Project and has been featured in such publications as Rolling Stone, Reason, Infowars, RT, MIC and The Tom Woods Show.

    Checks out.

    535nm for most/all of my greens.

    I do have one of the old 1000mw Wicked Laser blues as well, however, which I think is 445nm.

    Oh yeah. And my engraver is 100 watts of infrared (1084nm?), not milliwatts, although the range is probably a bit crap for this sort of thing and it's not exactly concealable. You'd also want to pack rather a long extension cord.

    What would be the type of laser that you should most keep away from camera sensors?
