Custom Night Vision | Data Sheets and Intensifier Tube Specifications 

This is great. I love playing around with your website and actually being able to see the tubes and their specs. If you're looking for video ideas, I'd love to see how you guys collimate tubes.

EBI is the background noise of the image intensifier and comes from the thermal emission from the photocathode. The EBI adds noise speckles to the image. These noise speckles are only visible in the photon counting light-level range because a tube has high gain there. EBI is usually expressed in lux and can be compared to the photocathode illumination from the scene. It’s important because it’s one of the means to achieve a good SNR but it’s not a performance determining factor by itself. A tube with high photocathode sensitivity but a high noise factor in the rest of the tube may still have a poor signal to noise ratio. Thus consumers should not focus on EBI specifications as a stand-alone measure of tube performance.

Great information! The LOST footage was genius! Aloha 🤙🏽

Thanks for the detailed breakdown. I'm slowly making my way into night vision and this information helps me understand some of the terms alot better.

Very informative… thanks!

Resolution is a measurement performed by people certified to do so. In other words, line pairs per millimeter specifications are determined by certified people looking through the image intensifier at calibrated charts. The procedure to determine this involves an operation voltage, color temperature of the light, a specific projection lens, a calibration target e.g., USAF calibration charts or Mire de Foucault charts, a specific and standard camera setup and input radiation to achieve best contrast. Basically, the person reads the target chart and determines the limiting readable patten and compares that to a calibration chart to determine the resolution. Of utmost importance in all of this is the Modular Transfer Function (MTF). A good MTF, enables the viewer to discern contrast. The better the contrast, the better the detail, the better the detail the better someone can discern objects in low light or high light conditions.

I recognize the Lost scene! Damn that was long time abo

Excellent video that explains the technical details. Very well done.

How can this video still be under 1k views!? A lot of great info here

I learned from this. Thanks.

Next day of I'll be using the builder ... I need to find my specs on the PVS-14 I have now ... the guys I bought it from were very helpful but nothing like ya'll are ... 100% buying my duals from ya'll... looking forward to doing business... stay safe frosty and free everyone... oh and

Awesome bro

What specs are good for low light rural operations where you must id things that are at farther distances vs urban where you have more background light to work with what’s the best specs for both situations

It's basically science

I'm very slow getting in night vision and I currently have a single monocular. I'm planning converting to bino, hopefully in the near future. With today's tubes, how important is tube matching now? Would the data sheet help get me close to a "perfect" matched tube?

the memes! lol i love them

I’m just here to argue. And boost the algorithm

So... Higher SNR Lower EBI =< 2.5 Higher LP which is the resolution Lower Halo Is that right? did I misunderstand any of that?

I understand the difficulty in a human being able to discern the difference in two relatively similar units, however I do wonder at what level do user's start to notice degraded capability? I'm sure it's going to depend on what stat you are comparing and who's eye ball is looking though it. At some point though SNR, Resolution, EBI and Halo all have to be different enough to make a noticeable difference right? Otherwise why charge more for better tubes and why rank them so stringently to begin with. Do your staff have any personal input on this, like at what point are the stats different enough to readily tell you are looking through a worse unit.

Im all about those celestial bodies.

Where ya'll located???

Much higher SNR of education in this video than T-Rex part 1, though at 7:10 you basically make the same point that T-Rex 🦖 did.

Thank you. Waiting two Elbits bought on your super web site shipping to Ukraine(through US citizen) for hunting Russian invaders. Thank you. 🇺🇦🇺🇸🏴‍☠️🤝 It’s a pity of different restriction between our countries borders and laws. Cause we all like America and thank Americans for biggest support agains pigs.

My break brain.
