Temporary blindness at 10km? With 15mW???


Is this possible?

This thing has the ability to blind people from several kilometers away and has been used to against a helicopter crew of the US military.
this makes me feel smart and good.
EDIT: not the thing about the military crew.

These days it is very difficult to challenge people to identify something online. If you post anything from the name, they can search for it. If you post describing words, they can search for those together. If you post a picture, you can do a reverse image search. If you leave any data on the image file, they can gather information about time and location of the picture.

Personally I recognised the picture as being an Nd:YAG laser and remembered reading something about disabling other laser related equipment with it. After I did a reverse image search I had the name and all the rest of the info available within seconds.

The best way to create a "game" such as this is to take the picture yourself and provide very general information (i.e. "damages related equipment" rather than, for example, "damages the photo-electric elements in laser range finders")

Obviously it's difficult to snap a photo yourself when only 22 of the ZM-87 were ever produced, but you know what I mean.

i just searched for "laser weapon" and i foud alot of information. i came across something and it looked similar to this one. the only thing i had to do is search for the exact name.

The Watt is a power measurement over time. This appears to be a pulsed weapon. High power pulsed lasers can have a very low average power in watts, but extremely high power pulses. certainly high enough to cause retinal damage. I'm more curious as to what the wavelengths are. It would have to be something non-visible yet still be able to pass through the cornea. Would have to be in the NIR somewhere.

I see.


You must have steady aim to shoot that beam into a helicopter.. then into someones eye.. who's is probably constantly moving all the time.

a dazzler doesn't have a thin beam lol they diverge allot aka not focused to "infinity"

EDIT: this is not a dazzler sorry for the mis info

Did you guys read this.
Strait of Juan de Fuca laser incident - Wikipedia, the free encyclopedia

Obviously I feel very bad for the pilots but it is very interesting to see the result of this lasers use. I can't remember where I read it but the laser does use IR although I'm bot sure what wavelength.

This isn't a dazzler. This is intended to blind people over long distances.. permanently.. By causing damage to the retina. Not disorient them.

This most likely isn't a visible wavelength laser and one that's VERY highly collimated.

Actually it is a dazzler. At longer distances it is used to cause temporary blindness and disorientation.

"Maximum range (blinding): 2 to 3 kilometres (1.2 to 1.9 mi) (5 km/3.1 mi if a 7x magnifying optic is used)
Maximum range (temporary blinding): 10 km (6.2 mi)"

It can also be used to overload laser rangefinder optics and heat seeking sensors.

You can't technically call it that but we're arguing semantics.

Dazzlers aren't meant to cause permanent injury to people. This thing is. It's a weapon. Not a dazzler.
