Okay so I’ve been saving my coin for a min to drop on this unit and by all means they are outstanding but each tube has a small blem am I just being picky here? just spending so much money I was expecting perfect.

It’s an optoelectronic system, it ain’t perfect. Some small splatter, some chicken wire, an odd spot is what you are going to get. I’ve got 2 pairs from TMVC and the one with greater small defects is actually the brighter and clearer tube. A dark room at night helps get the mount set and the diopter dialed in, but you see flaws. Take them out for a walk or a drive and you’ll never see the flaws. Actually, you can still see them if you look but the point is that the tubes let you see so much more IRL that the defects don’t matter.
The spec sheet or photos (or both) would help.
Image intensifiers are not digital technology, but more like an offshoot of old CRT TV tech. It is a very low-yield manufacturing process, and a huge number are fully scrapped. Setting aside the complexity of how you get high resolution and brightness, there is no such thing as a perfect tube; all have flaws of some sort or another. You can find "apparently" flawless tubes (the flaws are not visible) but they are there. And they are VERY EXPENSIVE as they are in demand.
A very nice moncular is in the mid-$3000 range. For a price comparison, broadcast quality image intensifiers (the clip between the camera and lens assembly... I have one) have apparently flawless tubes, not especially complex attachments at each end, are not waterproof or anything and cost around $8,000.
Aviation tubes are the highest commonly-available, milspec quality things because aviation demands everything be flawless...
No, because they fly around in empty skies, oceans, tractless desert and flaws can look like targets, other aircraft, etc. so confuse you. In ground mode, there's crap everywhere so it doesn;t matter. Stop looking at the tube, look at the image. Walk around and see things. You'll never notice the flaws in practice.

Makes me feel better lol I love them super bright clear image I was blown away, only reason I noticed the blem was when I was looking at a white wall in my house. It’s a super small black spec in each tube but I paid $10,000 for them and was expecting perfect. the blems don’t really bother me just wanted a second opinion on if it was normal this is my first NVG of this grade and I can’t wait to get out and shoot with them! I’ll post pics of spec sheet when I get home from this business trip and see what y’all think and I’ll try and get a pic of blem but idk if they will show up in the pic but I will try. Thank you guys!????
I had the same thought initially with my RNVGs, but after using them I don't even notice. Saved a ton and got higher spec tubes than if I had gone with a set without blems.
Please do NOT post data sheets online, it's an ITAR warning to do so. Just tell the main specs publically.
Oh shit sorry I wasn’t aware of that pretty new to the night vision world so still learning all this
Nope, not normal, or typical.
Instead, that is an extremely clean tube. Most have other anomalies, or several spots, or clusters of spots.

Awesome I honestly didn’t know being my first NVG but makes me feel a lot better about them, the left tube has a similar spec in the bottom left of the tube but is a little smaller than that one.
