Regarding black trails/streaks when looking to bright sources: What is happening is that the bright light is depleting the electrons locally on the MCP surface. While not ideal, it's one of the tradeoffs the comes with higher performance tubes.
Lol oh wow.. I was wondering what caused the random streaks. They go away after I shut the unit down because I'm close to a some what lit area. When back in the dark I turn it on and I can tell the streak is bearly there. Then the next time i use it, there's no streak
We wanted one of this to see the critters in our backyard. ruclips.net/user/postUgkxGix1RueFf66g4dKZ0w4Qsw_3Vv6Xqant The first thing that I like about this is that it has a rechargeable battery. The other is that it is small and fairly easy to use. The instructions weren't too great but we played with it awhile and figured it out. Can see very well in our back yard down to the woods which is roughly a football field length in the dark. There were certainly more expensive ones out there but this works for us and was within our price range. We have not tried the video recording portion and may update the review later.
Night vision will work underwater if you don't dive deep. The issue is more that light transmission dies really fast in water so night vision isn't going to be super useful for serious underwater work. I've never been a combat diver though so maybe they have some special applications where it works.
Not at all, we use lasers on steel all the time. Just make sure you manage distance and output so you aren’t 15 yards with a 90mw laser. Just use common sense and you will be good to go. If the bloom is bigger than the target, tone it back.
Laser doesnt burn the tube if it just flashes over it, falconclaw has a great NVG torture video, only a very powerful flashlight exposure for 5 mins straight, in the excat same spot left a permanent mark, same with the sun
I just got a set of Night Vision and it was my first one. I looked into the lens end by mistake thinking that was how to look through the goggles. I am wondering if I damaged my eye when I did that. I did not do it long, maybe six or seven seconds. But I thought that was how to use them. I just hope I did not damage my eye?
No dood lol. It’s a photo multiplier tube, photons go in the lens end, turn into electrons as they hit the cathode, accelerate to the micro channel plate where avalanche effect turns single electrons into many many more. Those then hit a phosphor screen which glows like an old TV set. Then a bundle of fiber optic cables twists the image from top to bottom to upright the image. Nothing comes out of the objective lens, photons go in that’s it…
I recently got a set of RNVG-A, L3 Harris unfilmed 2556 FOM 35.5 SNR. Love the image quality but the auto gating whine (it’s what most would call faint) is annoying on one of the two tubes 😐 Pretty much told, “that’s how it is, suck it up, send em back if you don’t like it…” the one tube is dead silent. I have an ELBIT that apart from hard auto gating is silent as well. Is it unreasonable to expect your tubes be be dead silent apart from heavy auto gating? I’m not talking across the room noisy, just mean you hear a faint 2.7kHz whine while wearing them without ear pro in a quiet room.
I had the exact same thing. I have extremely good hearing and can hear a lot of high pitched noises that others can’t hear. The high pitched automating noise was giving me a headache that I wasn’t getting with a different tune. I sent them back and the store said that they could not hear the noise.
@@rotorbobyep, it’s pretty faint. I guess the pisser for me is that 2 out of 3 tubes I own don’t make any audible noise. That means it’s possible to have a totally silent setup 😒
@@JamesReedy I’ve also had tubes that don’t whine. That’s why I thought it was pretty disingenuous of the shop to act like they had no idea what I was talking about. I will be getting another tube within the next couple months. Hopefully I get a quiet one. 🤷♂️
Why would u use NV in the daylight? Unless you're going into a dark abandoned building but even then you wouldn't be approaching the building with the nods down and on in the daylight.
It should be. Red headlights are not that bright to begin with, as they're made to make you see just enough. That said, make sure they don't shine right into the tube. The light bouncing off the ground should be fine as long as you're not staring at the light for hours.
Not being a prick this is genuine question! All that has been covered in this video then an operator steps off a helo into a battle zone with buildings on fire and explosions going off stuff like that. Are they just rebuilding there tubes more often or the milspec tubes can handle the light?
Professional end users definitely burn tubes much more frequently than a commercial customer. However, with that said the tubes have a microprocessor in them which allows the tubes to adjust to environmental lighting conditions. Concentrated light sources that are much brighter than the environment is where you run into trouble. For instance brake lights in a field where it is very dark could burn a tube where brake lights on a well lit road would not. It is all environmental based. We have an article on this on our resources page of our website that goes into this in detail.
The military does rebuild night vision often. Most of the companies providing repair services are composed of former military dudes who repaired night vision while serving. Your real concern as far as burning is leaving he tubes staring at the same direction for a long period of time. You are most likely going to burn it out by accidentally leaving it on, than in use. Lots of guys who own night vision play milsim airsoft and so they are shining lasers at each other and dealing with pyrotechnics, and you never hear of anyone getting their tube burned out. Granted, almost no one there is using a full power laser.
Our tubes might burn out more often, but it’s still extremely rare. You can look at all kinds of gunfire, lume flares, and explosions with no issues. Just don’t stare at them for a prolonged time.
Probably because you're using near latest gen tech, the public only has access to 20+ year old tech. I'm guessing they fixed the ambient light problem a while ago.
Conventional tubes and optics aren't ideal because they're optimised for IR and the lens blocks blue. It's best built from the ground up with a GaAs phosphide gen 3.
Watch at 1.5 speed, trust me
😂😂 Thank You!
omg, I did, lol
Should be default setting on RUclips
Hahaha

I was worried it was a symptom of low spec tubes haha

Then the next time i use it, there's no streak
That's what I'm wearing right now
IITs are actually super similar to your eyes, you can get minor retinal burn, like tube burn in, and both will repair/adjust themselves

i wonder if a person such as a diver underwater in dark water what would night vision do ?

The issue is more that light transmission dies really fast in water so night vision isn't going to be super useful for serious underwater work. I've never been a combat diver though so maybe they have some special applications where it works.
They have custom ones with photocathodes made for blue-green spectra.
@@DaveSmith-cp5kj not super useful? Please
@@Tattlebot Sounds like you never dived before. And no, spectrum does not increase light transmission. The issue is lack of light intensity.

Do you recommend not using IR lasers with steel targets to prevent the laser burning your tube?
Not at all, we use lasers on steel all the time. Just make sure you manage distance and output so you aren’t 15 yards with a 90mw laser. Just use common sense and you will be good to go. If the bloom is bigger than the target, tone it back.

Is it bad using nods during day with the objective lense and the tiny hole?
Can but highly not reccomended. Can dmg it.
Why would u use NV in the daylight? Unless you're going into a dark abandoned building but even then you wouldn't be approaching the building with the nods down and on in the daylight.

I should also add they aren't fixing the I^2 tube, if there is a blemish they are removing it from the housing, and putting in a brand new one.

Dont tubes get burns/blems even if they are off? Just use lens covers lmao

No
