AN/PVS-14 ID

Postby lcpd452 » Sat Oct 09, 2010 11:06 am

Just bought a new AN/PVS-14, can anyone tell by the tag on the housing as to what type of tube it has?, serial is 76857,
MFG IDENT :13567, and NSN:5855-01-432-0524, and the tag reads: AN/PVS-14, this is the second one I bought, really like these, I would like to remove the eye piece, and get the spec's and post them, but I have never done that before, is it hard to remove the eye piece on the PVS-14?, I have been reading that they are purged at the factory, can this ruin anything in the unit??

You will need to get the numbers off the back of the tube in order for a positive identification to be made.

1) Look through the ocular lens at an angle while and copy the numbers off the back, you might need to shine a flashlight at the ocular while doing this.

or

2) Unscrew the ocular (counter clockwise) and copy down the numbers off the back.

Absolutely no harm can be done by removing the ocular. If there was, I and a bunch of other would have ruined our unit by now. I remove lenses on various units on a nightly basis to switch between camera relay lenses and oculars.

I didn't remove the eye piece, but I used a weak pen light, the tube had: V 339891, CAD 0827, and MFG 13567, that number matches the tag on the housing

Looks like you have a nice ITT OMNI VII MX-11769 "PINNACLE" tube.

MFR 13567 - Is the cage code for ITT

V 339891 - Not sure where the "V" fits in but there seems to be a 3 missing i.e. should read SERIAL NO. 3339891 not V 339891.

CAD 0827 - The date it was accepted under the contract specs i.e. date of manufacture. Your tube was produced the 27th week of 2008.

Was the CONTR. NO. missing? It is inline with the other numbers and should have been easily visible.

I looked at it again, the serial is 3398981, I was missing a number, did not see another "3"

Well that explains why where the 7th digit was. Where did the V come from. and is the CONTR. NO. missing? It is inline with the other numbers and should have been easily visible.

I could not see that number any place, but Im just looking though the eye piece, it may be on the tube, but I can't find that one, the "V" is like in the same row as the other numbers, but it's seperated by a notch on the tube, I looked at it again, and it is a "V" with white color in it like the other letters, I tried to take off the eye piece, but there must be some type of loc tite on the threads, by any chance, would you be able to e-mail me a photo of a tube like mine, so I can see how the lettering is, and what I should be looking for?, thanks for all your help!!!

Did a little more digging and found out exactly what tube your unit has. Your AN/PVS-14 is fitted with a F9815DTG2 tube. I've attached the minimum/maximum performance specs for the F9815DTG2 image intensifier.

Here a direct quote from ITT regarding your particular unit;


"This particular image intensifier was shipped to NVS (DRS Technology) in a F6015DTG2 system.

Built July 08

This is a OMNI VII design tube but it does not meet the full OMNI VII spec"

Wow, thank you for finding that, it seems to be a good tube, I have compared it with my ITT NE14-11, it seems to be on par with that one, the only thing is, the halo like around street lights is smaller in this unit, compared to the NE14-11 unit I have, that is the company my buddy buys all his NVD's from, I remember him saying that a while back, need some advise, Im thinking about buying another one from Optics Hq, from what I have been seeing on these forums, he is the man to go to, for a hand picked unit, thanks
