About six months ago I purchased a harder digital fom 2600 tube and a pvs-14 body kit from Europe. It was easy to install the tube into the body kit. However despite the high specs of the tube, I was a little disappointed with the views it gave. In particular stars were noticeably less pin sharp when compared with my actinblack pvs-14.
At the time I assumed that it was an attribute of the nv tube. However, subsequently I read some threads on specialist night vision forums which indicated that USA milspec lens gave materially better results than the “commercial” Optronics Engineering pvs-14 that I was using.
A couple of weeks ago, a European vendor started selling Carson milspec pvs-14 body kits (legally!). I decided to check out whether it was the quality of the glass that was giving the disappointing views. I received the Carson body kit this week and transferred my fom 2600 tube to it. The results are amazing. Stars are now pinpoint across the field of view, better than my actinblack and in indoor testing the additional sharpness and resolution of the views is very apparent. Clearly it was the commercial glass that was the issue not the tube!!
I just thought I’d post this info - particularly for non USA night vision users as it’s an additional consideration to improve the nv views.
