Night Vision Goggles

[Reiign]

the reviews are pretty good on them. I might grab one and see how well it performs. Its pretty much exactly what i wanted and its a kids toy lol

When I want in complete pitch dark to enlighten the aria I am watching with a 3W infrared laser 980nm laser can I see the result with night vision goggles and do I need on top of them the protective goggles and will this work. I assume the night vision goggles do give no protection to my eyes for the 980nm in case of reflections. Big question is will they still work when I put the protective goggles on top of them. Or I am missing something?

And my second question can a FLIR adapter for your Android phone see also the heat beam of a 3W 980nm laser?

that would actually be a pretty cool way of having fun with ir lasers lol

In combat they using this technique to point to each other the enemy without the enemy knowing where they are. Visible lasers always immediately telling where you are positioned.
The same for hunting it does not scare the animal with normal visible bright light.

No. A thermal camera sees things in the range of about 3-12 microns if memory serves. Even a 10.6 micron laser beam does not show up though. The laser does not heat the air, nor is it scattered by the air.

If it heated the air then there would be no energy left to pop balloons!!!

The camera is probably better than gen 0
and 1 in every way except there is no
viewfinder to use it as "nightvision" in
the classic sense.

Gen 2, not a chance. The microchannel
plate in the gen 2 scopes amplifies the
light 20,000x. A CCD won't "hold a candle"
to it.

Thanks. Thinking of making those ghetto nightvision things using a camera and IR illuminators I have a small monitor that I can use for that.

Let me know how you go djQUAN a nightvision/thermal diy would be pretty badass!

Cyparagon what means that I could see on the FLIR only the point where the laser hits a solid surface and releases its energy. How in a misty environment or in the clouds where it bounces and interacts with the water droplets?

 

[Cyparagon]

Maybe. I have never pointed a CO2 laser in mist, let alone inspected a CO2 laser in mist with a thermal camera. CO2 laser + FLIR is bad, because it can damage the sensor. Both times I have used FLIR and CO2, mere specular reflections have resulted in severe image burn-in that fortunately went away after a few hours.

Cyparagon thanks for that info I will watch not to destroy anything and be extra cautious with FLIR in combination with CO2 lasers
