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.
If you actually want to do this, look at the NUBM44-V2 laser diode. 7 watts of output power and around $30 on eBay. Another $50 or so for a driver, heat sink, and lens and you can burn out cameras in seconds (you can also burn out your eyes so a good set of laser goggles is essential).
Laser googles lol
"My eyes! The Googles do nothing!"
Oops, fixed lol
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.
This is why I advocate for the anti-surveillance method of "hit camera with big stick"
"Heave rock at bad thing" really does cut to the primal core of the species. Thog not believe how much copper is in mammoth.
Reflections can also blind, so make sure no-one, including you, are uprange, or siderange (to stretch a wordform to breaking point) either.
~~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
Oi mate you got a loicense for that diode
Don't even fucking joke
"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.
We were promised lighsabers and yet we can't even have a cool torch!
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:
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.
Yeah engravers need near focusing.
What would be the type of laser that you should most keep away from camera sensors?
Brutal honesty here: if you can't figure that out on your own, you really really REALLY should not be playing around with high power lasers.
Okay, but what's the answer to my question please and thank you /s
Silenced .22LR rifle.
Also, you'll want one with a fair bit of power to it if it's going to do any permanent damage.
A typical 'safe' 5mw laser isn't going to do shit, regardless of the color/frequency.
What kind of wattage?
