Those are fantastic specs. Very nice on paper, and the fact that you're happy with it means even more. The calculation for FoM seems a little off though, I imagine you doubled up the # shown for PC sensitivity. Looks like FoM is 2202 (and the important side of it, S:N is very good).Really happy with performance, but I don’t know enough to know what’s considered amazing.

You’re right, I just wrote the wrong thing down! Still figuring out what’s what on the sheet. Glad to know it’s considered a great tube, even though I didn’t have concerns.Works out to 72LP if you divide his FOM by his S/N. Probably read the wrong column.

Have looked thru many thin-filmed elbit and (20,22) UA L3 tubes, these are the best Ive seen. The FPN is non-existant like thin-films, with all the defining characteristics of unfilmed.
I've done a few transactions with Nightline at this point. They're website isn't as developed as some of the newer businesses, but dont be fooled; solid business, has been around for decades, and very easy to deal with.
Would be interested to look through yours vs mine. I have about identical specs from TNVC and my tubes are the 18um. Extremely happy with mine. I honestly wonder if there is a clarity difference in the 24ua to the 18um. Again almost identical specs. Was there a significant upcharge for the "24ua"?
We can assure you there are no clarity difference between a 18um and 24ua with all specs being equal. Some fake news on the internet spilling this along with unfilmed tubes degrade after 500hrs. It's unfortunate. Thank you for the business Sir.Would be interested to look through yours vs mine. I have about identical specs from TNVC and my tubes are the 18um. Extremely happy with mine.

^^^^this is exactly what I was told by the first vendor I spoke to when I began looking into Nods.We can assure you there are no clarity difference between a 18um and 24ua with all specs being equal.

Right on, located in Indiana myslef. Still wondering, Did you end up having to pay a premium for the 24ua? I believe my setup through TNVC was about $9k, and they didnt upcharge for the specific minimum specs i requested.Im in lower NY so if you're ever in the area, I'd be happy to do so. Like I've said, seen more than a few sets of 20 & 22 UA tubes; these 24s are definitely nicer.
So I don't have night vision of any sort so I can't post specs.
Trying to understand what each of the specs mean. Like on these are higher numbers better or worse? Or does anybody have a source that explains how the different numbers affect the final result?

For anyone learning NV specs I suggest checking out Nocturnality's Instagram. They do a good job of talking about specs and then showing comparison examples so you can compare real world spec and tech differences.

Imo the n-vision zone 3 blems are the best deal in night vision other than maybe winning the XLS supertube lottery. They guarantee SNR > 30 and let you handpick from what they have available. My tube is from a 22um batch I think.3300 is a good price for filmless.
Are you sure you have FOM 2829...not looking for any trouble here? I know people like me with relatively low posts get flamed for asking questions like this.FOM: 2829.6

VENDOR: JRH, satisfied. Previous tubes had lower ebi at .2/.3 but lower SNR at 32/34 and mismatched HALO which I found distracting. These have much higher SNR, matching halo and good but not as good EBI. Happy with new tubes, great deal of clarity, waiting for dark night to really watch them. Would like to compare the polycarbonate lenses against PVS-14 glass someday, some polycarbonate actually have higher light transmission than glass and less glare. I would assume this is the polycarbonate in my BNVD UL. Blem doesnt really concern me as it disappears in almost all actual usage and I would take a blame tube with higher spec over non blem with lower spec anyday. I do not like FPN though, dealbreaker for me.
Here is how you do it.Sheepdog697 asked-
"Nice specs! Did you have to pay extra to get hand select tubes?" (Sorry don't know how to do quotes here)
No, we do not charge for that. The higher spec L3 filmless tubes do cost more however. -And take forever to get...
To insert quotes you have to go down to the box and press the Insert Quote button. You can also clear out old quotes in the box as well.Thanks.
I'm showing "55 insert quotes" in that little box LOL. I've been doing something wrong for a while now LOL.
Yes. Press the Insert Quotes button in the box on the bottom. Then click the Remove in the box that pops open. Works about the same as far as I can tell computer or not.Can I clear the old quotes out somehow?
