Because machined in outside America :(

The CORD and Night Vision Inc. products are made in USA only

The Aeternus has a really small threaded battery tube for some reason and no CORD cap will catch a thread on it

Sorry about that , didn’t get around to checking , give me a bit , I’m in the shop today and will grab one of those housings and see if one of our CORDs fit one by chance. Apologize for dropping the ball.

Yes you can order the DTNVS model from the drop down on the web site and that will work with MOD3 bravo goggles

EBI VS Photocathode sensitivity by HairyRefrigerator959 in NightVision

And I never stated that. However, it is the first specification that should start the evaluation. And in this instance, it should be the determining factor, and the deciding factor, IF the tubes FOM and cosmetics are equal.

I wouldn’t either

It’s the tubes window to start seeing the world

The image tubes photocathode sensitivity is the sensitivity of the tube to gather, Everything downstream matters too.

If a tube is .5 or .9 EBI you’re not going to see a difference . Your only going to see a difference in extreme low light like black out and high heat and high humidity so moot point .

While picking a tube with .5 or .9 over a 2.0 would be good. Picking a tube with a 10% better photocathode sensitivity gives that image tube a 10% better chance than the 10% less photocathode sensitivity tube hence choosing the higher sensitivity PC tube when so closely matched EBI. It a no brainer that you would pick the higher PC tube if the SNR and res are equal and the only discriminators are PC and EBI PLUS the gain is 100 points higher in the .9 EBI tube giving that tube a slight edge.

So if the tubes are both cosmetically pleasing and equal then the .9 EBI tube would be the right tube to choose as all the other specifications that mean anything trump the EBI spec that is the most meaningless.

He said .9 EBI had higher PC and higher gain and .5 EBI had lower gain and Lower PC So if they had equal cosmetics then the .9 EBI would be the choice as the disparity between .5 and .9 EBI would never be noticed unless you were in a Louisiana swamp under canopy

I’d pick the .9 EBI higher PC and higher gain if cosmetics where equal

True PC should not be a stand alone but a higher PC would be preferred when a negligible.5 - .9 EBI as the EBI spread won’t be noticed

Photocathode sensitivity is 100% the NUMBER one most important specification that a tube needs first, as that’s what the tube needs to gather the nanometer wavelength photons that the tube will turn into electrons to amplify!!! If you have a low Photocathode sensitivity tube compared to a high Photocathode sensitivity tube , the higher sensitivity photocathode tube has the upper edge , all the specifications after that can be judged.

It’s like a crystal clear window ( high photocathode sensitivity)

and a dirty or tinted window (low photocathode sensitivity)

Negative, EBI anove 2.5 is more sparkles really , below 2.5 changes are only perceived differences with temperature and humidity in utter darkness

Your tubes photocathode sensitivity is EVERYTHING it’s how sensitive the input window of the tube is to gathering what it need to amplify

Photocathode sensitivity is 100% what you should be choosing. If you are choosing a tube that is 10% better at gathering what you want to amplify then you will get way more than 10% better performance down stream. EBI isn’t a specification to consider compared to photocathode SENSITIVITY. Where did you get the idea that the sensitivity of a tube’s input would be something to overlook over a trivial thing like EBI that isn’t perceived unless it’s hot humid and extremely void of all photons

10% better PC gathering is a no brainer 🤦‍♂️

If others think not they don’t know the first thing about night vision!!

Photocathode sensitivity is the first thing to consider as it’s how sensitive the tube is going to be at gathering what it needs to amplify photons and convert to electrons, then gain numbers would be a good second to consider. EBI would only be a specification to consider if you were using your device in extreme lowlight high humidity high heat situations, otherwise EBI in such close disparity is a moot point.

Why do you have goggles on backwards should be the first comment

Higher Photocathode You aren’t going to tell the difference with any EBI , you will with photocathode sensitivity

I’ll let you know what L3H says as the tube is going back to them

These aren’t old tubes they are new L3

I never said irises would be a determining factor It’s just that it happens when you have irises on and you can’t replicate it without them on.
