Laser Eye Protection questions

Thanks for the more serious reply. You are correct, getting a fast response time to the targeted narrow band laser illumination is hard. Glasses with fixed narrow band filtration are a better bet.

That said a good project would be an automatic localizer for the source attached to a high capacity paint ball or rubber pellet gun.

The vendor sells glasses specifically made to protect against attacks using common green lasers in the category "Laser Strike Glasses"

You probably have your glasses by now, but here is a link to one source of protective glasses.

Laser Strike Glasses

Dispersal medium—dense smoke or fog—provide best protection against a generic visible laser attack. Goggles—video camera to video display technology—isolate the eyes from direct exposure. IR equipment would allow illuminating a target and viewing said target through smoke or fog.

GENESIS ILLUMINATION INC. Stun Ray with IR target acquisition system could be useful as counter-battery. A Xenon photoflash output is channeled through variable directional optics to temporarily incapacitate an opponents optic nerves from seconds up to a duration of twenty minutes.

This is an old approach—might could cobble such from over-driven LED as some photo-flash enthusiast have more recently done. Here is a starting point:

“A flamethrower drone might also be effective...”

Two points...

1) How long before Antifa deploys these to burn down police stations, court houses, etc?

2) I want one.

Thank you! I was starting to get that very same vibe from that site.

eye protection is rated according to the nm (nanometer or wavelenght) of the lasers that it protects against. Any respectable laser protection will give a lower range to upper range for the protection. Compare that against the following

Green laser - 530 to 570 nm (most dangerous to the human eye)
Red laser - 630 to 670 nm
Blue laser - 350 to 490 nm

I recommend that the laser protection state a range of at least 300 nm to 800 nm. Understand that I am not an OSHA regulator or a laser scientist so do your own research.

“If I were in an area where I had to worry so much about criminal thugs pointing lasers at me then I’d stop going there or move before I’d start wearing goggles all the time.”

The only reason I’d wear a set of protective goggles is if rioters showed up in my neighborhood. I’d need the protection if I needed to defend the homestead. Slim chance that’ll happen...but you never know.

“That said a good project would be an automatic localizer for the source attached to a high capacity paint ball or rubber pellet gun.”

I was thinking more in terms of the automatic anti-sniper weapon, which locates mussle flash or traces back the trajectory of the round to the shooter, and the fires back. This already exists.

These prism laser reflectors are snap on. Put one on your tactical helmet and you would shine the laser exactly down the path it came from with negligible power loss.

Would be a real deterent to the laser peeps.

Is there a version that just launches an angry skunk or two at the person with the laser? That seems like it would disperse the Antifa clowns quickly and make great videos we could all enjoy.
