Night Vision PVS14 gen3

-----------------------------------

Vand Night Vision Gen 3 Omni 7 cu filet c-mount ce poate fi adaptat foarte usor ca si ocular Night Vision la telescoape sau obiective foto.
Am verificat dupa seria tubului si caracteristicile de catalog sunt urmatoarele:
--------------------------------------------------------------------------------------
 ANVIS MX-10160C F9800 Thin Filmed Autogated OMNI VII Image Intensifier Tube - shielded = aviation tube
Resolution 64 lp/mm
Phosphor P43
S/N ratio 28+
Photocathode sensitivity 2200+
Sensitivity at uA/lm@830nm 120@880
Gain fL/fc 50000 - 80000
EBI (x10^-11) <2>+3)
Din poza facuta la ecranul tubului se vede un singur punct in zona 1 dar care la observatii nu este detectat pe cerul negru, deci personal nu m-a deranjat absolut deloc.

Tubul l-am fosolosit cam 100 de ore deci este foarte departe de durata de viata.
Se pot accesa chiar si reglajele de intensitate si sensibilitate direct de pe tub, detalii in poza.

Nu fac schimburi, se vinde doar ce este in prima poza, fara alte accesorii dar pot ajuta la adaptarea lui pentru astronomie cu costuri foarte mici.

Pretul SH pentru tubul Omni 7 AVIATION gen 3 thin filmed este peste 2500 EUR.
Pret cerut de mine = 10000 lei fix, cu testare in Bucuresti (doar cash).

update

-----------------------------------

Am cerut parerea unui specialist pe forumul din USA (Eddgie  - cloudynights.com)
https://www.cloudynights.com/topic/923365-is-this-omni-7-or-not/#entry13467868
==============================================================

You have a civilian version of the  (non-contract) ITT MX-10160C  (F9800VG) 272692-35 autogated tube with metal EMP shielded casing. It has the same minimum specs as the military tube. It simply was sold on the civilian market. It is electronically and functionally the same. 

 Don't let the talk about not  having manual gain deter you from using this tube. Some of the best views I have ever had were using an F9800 version of the military tube. 

If you were in the US, if it is bright and blemish free, it would be worth about  $1500 unhoused. In Europe I would think it would be worth much more than this. (New in the US, it would be about $2800 to $3200). 


The reality though is that you might pay a lot more for a tube that does not perform much better than this. The F9800 was a top of the line thin film image intensifier. This was what was given to military pilots flying multi-million dollar aircraft. They got the highest performance tubes of the military standard issue tubes. 

 

I would say that the performance would be better than some of the filmless tubes out there that I have seen but since there are no filmless tubes in Europe, getting a tube much better than the 10160C/F9800980 VG or F is going to be mighty expensive and the performance difference will likely be far less than the extra money you would spend on it.
