Oh my, 500 likes until part 2 milestone. What an honorable shill by community. LIKE if you want to see Photonis ECHO, REPLY if you want to see some equivalent Gen3. *As a side note to USA community - we are in EU, so we can't get hands on your Gucci L3 wishes.
@@fluffyrider9467 They are more sensitive. Most of the things he does in this video would almost instantly ruin my tube. I get those tracing marks from fractions of a second of exposure to all kinds of light sources, even the moon.
This is insanely useful content, especially for night vision airsofters who deal with lasers being shined at people’s faces. Props to you for sacrificing expensive tubes for science! Blows my mind eye safe lasers don’t instantly destroy NVGs
This is valuable information for the entire night vision community as a whole. I think we need to test a bunch of different brands of tubes. Hopefully this will catch on and the Riches will assist in the research.
I can confirm that Omni 8 GP tubes are blemished instantly if straifed with a PEQ15 on vis high. Gen 3 has a higher light amplification and will blem way quicker than this Gen 2 tube in the video.
I turned the lights on while wearing my L3 unfilmed and it took me a few seconds to realize what I did cause everything just looked the same as it did the lights off, except a little better lol. No negative effects.
@@jackdangers3292 I don’t even think it triggered the auto gating. Auto gain kicked in for sure but it may have not even crossed the threshold of too much light to make it start gating. It was with a 14 so when I hit the lights I could see fine with my unaided eye, as intended, and the NV image through my aided eye also just looked like totally perfectly fine and clear. Everything looked normal and great lol. So it took me a few seconds to be like oh shit I’m using night vision with the lights on 😂😂. Totally not a problem at all.
Interesting… the time stamps I thought were on purpose. It’s “1 minute fourduh five” and there’s more but I thought for sure that was a joke. I just came here to say I loved the commentary and saw this comment lol. The one about the poors coming after you with their flashlights cracked me up
The cathode was Permanently damaged after the 1st tests. That is evidently by the highlight burns that disappear in low light. A screenburn will always be visible, a Cathodeburn only during highlight. The reasong is that even a burned cathode can produce some electrons and when the surrounding (unburned) cathode also produce obly some electrons the diference isnt that big. Only in highlight the diference is big enough to show on screen... Also blackboxing only helps against Catgode damage, and on gen 3 the best effect is with gated tubes...
As a vet who had someone kick on a light generator while wearing my NOD, i can safely say it doesn't matter what the light source is. You are gonna rip those things off your head so fast and run away holding your eyes. It's PHYSICALLY painful. You FEEL it. The back of my eyes had a dull, hammering feeling for about 30 minutes after and I was COMPLETELY BLIND for about 5 minutes.
Damn, this was hard to watch but it was really fascinating! Thanks for doing these test as I was always interested on how much abuse an intensifier tube can take.
Thanks for making this, my unit has 2 small blems and I've been afraid of making it worse but maybe I shouldn't worry so much. I'm still going to be careful with it tho.
Fire(and all heat sources) give off a lot of infrared. But open flame is basically like a giant infrared emitter, it’s how the heat transfers through the air after all
Nearly didn't subscribe bc I thought I was watching brass facts (in which I'm already subbed). It's insane how similar you sound and the quality of content. Looking forward to more 👍🏻
Amazing tests, thanks for doing it! It makes the purchase of night vision feel less like buying a fragile glass jar that would break at the slightest accident
Great video, great information. Can't wait for the modern NVG video. I'd prefer Photonis, but would be happy with whatever. I am now going to go stare at the sun with NVGs.
Thank you for all the work and sacrifice and put into this test. Very insightful seeing how these real world concerns effect actual usage as well as comparing their results from old to new tubes
Also you have to consider what light you are looking at. Home LED is well and good, but a 1 kW high pressure sodium lamp has its peak emission in a NIR sodium line. HID and incandescent have multiples of energy in the NIR range. This coincides with another reply warning of fires.
We should crowdfund this test on a modern tube because just running high IR across a reflective surface will leave dark snake trails on an l3 tube, so 30 seconds would absolutely mess it up.
It seems to me people destroy them by leaving them on pointed at a static light source for an extended period. I'm glad to know short exposure shouldn't result in insane damage fast.
You should do one more test- take a night vision device with a tube inside, have it turned off, and place it outside with the objective lens pointed towards the sun on a clear sunny day. People have reportedly suffered permanent damage to their tubes photocathode or phosphor screen due to this, but I'm unaware of anyone testing this yet.
@FalconClaw thank you. I'm an Optics tech, work on these things in the military. From what I've been told, know, and heard, it shouldn't happen. L3 stands by this also and apparently one guy from them said it cant happen. The photocathode and phosphor screen are only active when they are energized with a supply of power from the battery. Otherwise, both are just walls that nothing can pass through. Imo- large amounts of light hitting the photocathode shouldn't do anything to it, but MAYBE, over a long period of time like a few hours, the sun's rays will most likely collimate and physically burn it, causing a permanent blem. I heard stories of this happening with day filters on, specifically those with one hole in them. More ideas- you could try this with and without the daylight filter, and with the device properly focused to infinity and completely out of focus for a total of 4 different scenarios.
While sitting in Kuwait waiting to launch into Baghdad, my 240 Gunner thought it’d be funny to shine his laser into my 7 Bravos…. 😂. Guess who got a brand new set of PVS14’s? This guy.
Very cool video! Super great information with commentary that's entertaining as well. I'm currently trying to build a PVS-14 over time due to crazy costs and budget. That being said I'd definitely run that tube with it's end results. Especially if I can find it at a good price. This video is vital information & makes me feel not so bad about looking at older tubes for purchasing haha. 10/10 got a subscriber this time.
I have a high end Omni 7 with a big round laser blem in. I use it as my "fuck around" set. Blems happen quite quickly there with laser in complete darkness, or in daylight.
I have always wondered if it was possible to see gamma radiation with NVGS. There has been a few cases where you could see a gamma particle hitting the camera sensor
Yes you can see it, but its realy inefficient. The radiation has to have the right energy (extra strong), direction and your tube has to have the right gain settings and thr screen material has to match. As a fact most tubes seem to be more sensitive to temperature (wich manifests in noice) or beta radiation (a problem in some old Gen 1 devices with radioactive lenses) than to gamma radiation. In essence when you realy see the radiation, you are dead...
it should be noted that on an elbit wp tube, that flashlight test would leave significant streaking and burns spots, that would obscure vision for a few minutes at least. lower spec tubes are actually able to eat a significant more amount of light with no marking.
Same,just last nite while stargazing while walking it happened twice too me when i took in a little too much streetlights acrosss the cemetary,i just cover the lens and it goes away,weird right?i got a wolf14 gen2+wp,you?Just asking to see if maybe a agm thing
@@lock7852 Its common on all but L3 unfilmed honestly. I get it on my Elbit XLSH high specs and photonis. Im glad it goes away but 1st time you experience it, freaks you out. Someone told me its common on older tubes and as they warm up the problem goes way all together.
@@dang879 man i appreciate the info,it was funny seeing your comment as last night was the 1st time it happened and then did it twice and was hoping its no biggie,im on my 1st nod so still learning alot, thanks again man🤘
Anymore tips like "black boxing" the nvg setup? I never heard of that before and was super interesting to see work. Thanks for the video and sacrificing a tube for science!
Most NVD/G’s come with built in ABC/BSP aka Automatic Brightness control and Bright Source Protection. One changes the amount of Volts powering the NVD/Gs themselves hence dimming them and the other recognizes dangerous magnitudes of lights and cancels it out by eliminating the portion where electrical light energy from the photo cathode gets sent into the MCP where electrons are multiplied. Awesome tests, fascinating stuff
There is ABC or auto brightness control, these are very common on modern gen 2.5 or gen 3 tubes, they can work fine in room light. Different techniques exist for controlling the brightness for damage mitigation, such as MCP bias current limit, photocathode to MCP bias current limit. The phosphor is usually what gets fried, but I am not aware of any circuitry in popular tubes for controlling the vtage or current in respond to over bright scenerios. The bias for phosphor is on the order of 5000 volts.
@15:21 and many other side by side comparisons tube is rotated 180, 90 etc just saying. Please try to keep tube at same degree for quick pattern reference for us awe tistzzz. lol. Very good and informative content thanks
The content is great stuff but the tone of the video was awesome! As an EU resident, I'm looking forward to buying my first tubes from you guys in the near future
Here's an idea for you (judging on the wall//sun experiment(s)); Try finding//setting something up that has//gives off high emissivity black-body thermal-radiation and set the tube next to it for a bit.
Like, heat up a piece of limestone or even a spot of asphalt/piece of cast iron and set it in front of // kinda close to the unit and ofc try to point it at the hotspot
Dude way you put in that helmet in tarsh U r a lucky man dude really airsoft guns , and all gear like US special force it's my dream really this item's no here in India 😔😭
very educationnal video: what you have to learn is about phosphore properties (why there are black dots aeras you can only see in certain conditions) and what is called " fovea", a known phenomena of our eye that is also visible on tubes when exposed on a light image for long ( and that could disappear with balck box ).
This is very cool! I'm curious about how older gen tubes will fare against light tests like these. I'm a poor with a gen 1 magnified monocular and I'm wondering how it might fare mounted to a rifle for milsim. Just the idea of some OPFOR panning a gazillion lumen light across me makes me anxious. Does anyone have any advice? Besides uh... getting a better job
Because i love my shotgun and all the fun ammo types it comes with. I was curious as to how a flash bang might hinder your vision through the tubes. I was always thinking in a no light close quarter situation, aside from throwing madd 00 buck down the hallway, a quick flash bang round to start would get the disorientation going.
Have you tried 365nm UV as an illuminator with Photonis? it should have out of band properties against GaAs. Even better, gear contains heaps of long chain polymer and fluorescent dyes which will give FLIR like contrast. I've tried asking a few different channels about it, but they don't seem to show any enthusiasm. $10 will get you a 3.7V torch with a quite good bandpass filter which blocks visible light well.
Yeah try that with a 4W 445nm high powered blue laser. What I gathered here is that if it's not safe for your eyes it's also not safe for night vision. This is definitely not a safe laser for your eyes and can easily be used to start fires so use proper laser safety goggles not the cheap ones.
