[ARCHIVED THREAD] - Non IR lasers and night vision

Posted: 7/25/2005 9:04:55 AM EDT

I'm curious. What would a normal laser look like under night vision? Would it be too bright or is the light local enough to only show the laser dot against whatever else you are seeing through the night vision? I'm just curious because my EOTech isn't night vision compatible but I added a Streamlight. I'm not really concerned with the visiblity of the laser, more if it is "toned down" enough not to blind you.

Thanks,

A visible laser isn't to bright (as to blind you) when viewed through GEN III NV.

I tried my OTAL with a PVS14, it was actually usable. I didn't play with it long enough, after couple of seconds it had started to burn a dot on the PVS14 so I decided to spring for an IR laser instead.

There is no visible difference between an IR laser and a visible laser when viewed through NV that I have been able to discern. If you picked up two handguns with crimson trace laser grips for example with one IR and one visible I don't think you could tell the difference through the NV, both will show a bright full beam under conditions with littel ambient light, such as outside the city limits in a rural area.

Where I've had the distraction is I often work with both eyes open (one eye covered with monocular) and it is then that when your non NV aided eye will pick up the visible laser and for me it becomes a problem.

ETA: I should have mentioned that regarding the toning down. If you hit an object too close to you with the IR it will bloom to an uncomfortable blinding level immediately. Experimenting with equipment is really important when it comes to NV and related items.

My visible OTAL and my PVS7 do not work well together. The 'bloom' tends to completely obscure the target at 100m or less.

Hmmm, I wonder what the green lasers would be like?

At one point WES GRANT (IIRC) was talking about having a visable laser made that had an adjustment so you could turn it down for NV. Anybody know what came of that

Well, we use ANVIS 9 night vision goggles when flying and I was told they are Gen 4. ( got 5 pair through US Gov.). We also have an IR laser designator on our FLIR unit. When activated you can see the entire laser beam and not just the reflected dot while viewing under NVG's. Now when a Crimson trace laser grip laser is activated I am only able to see the reflected dot and not the entire laser beam for some reason ( I only wear them and am not an expert).

CTC laser on an M9 showed up just fine using issued NVG.

Maybe I need to be on the other end of the laser like you are. From wearing the NVG's and looking out in the distance i can't see the beam. Now the IR beam I can see. I will have to try it again next time I work. Weird

I could follow the laser out to about 300M so not sure what the prob is on your end.

Me either. The goggles are top of the line ANVIS 9 's. Like I said I will try it again and see what i come up with.

photo taken using PVS-14's
The dust in the air makes the laser stand out with the naked eye but I don't think that should be a factor with the NVG, could be though, maybe someone who knows the science can say...

[#13]

That may be it. I know you normally can't see the beam with naked unless you have some sort of medium in the air (dust, moisture etc.) I was using mine in the field next to our hangar which is all grass. Maybe one of the Mr. Wizards we have here can clarify this for us.

visible lasers are just at a higher wave length the human eye can see them. IR is to be covert.

night vision picks up a wide enough range so we can see in near total darkness (outside). as far as tube damage goes, any artificial light souce can damage a image tube given the right circumstances.

i have been using a visible laser on my supressed Walther P22 and it works fine with the pvs14. it's kind of a weak beam though. maybe the high end, high intensity visible lasers are too much light to work well.

how's this for an IR laser?! it's a 85 milliwatt laser the beam goes from .5 deg out to 7 degs. so it can be pinpoint for aiming or a flood beam out to 1000 yards. they should start popping up soon.

Ok you have my intrest.

Where can these be aquired??

And what would one cost??? Also how do you zero it? I dont see any adjustment knobs?

Actually the unit does NOT have a pinpoint dot as a typical laser does, it is not used for percise bullet aiming. It is after all only a high-power illuminator to see your bullet impacts and targets of opportunity!

It has a 1.5 degree beam at the smallest focus and a 11 degree beam at the largest. Thus, there has not been a need have any zero adjustments, the beam is always wide enough to illuminate a target from 20 meters out to 1000. It utilizes a steel ring with an adjustable windage setting though. Hope this helps.

OK, so how much are they and where can they be bought from ?

Thanks,

Here is a pic of a rock formation at 500M. Thus far the TRUE effective range for this unit is looks to be around 600M. The pic below was taken with a D-760 (6X) with NO moon at 7000ft elevation. An EXTREMELY dark night. I am really impressed with the edge to edge sharpness of this illuminator.
