Re: Night Vision Goggles
Question for you, Are you completely wedded to dedicated Dual tubes? There are several systems coming that put Monoculars together into Binoculars. these will have a versatile advantage over the Dedicated Systems and what we are going to offer will be something that is collimated so that each tube's optical path will be aligned. these systems (assuming your using two $3400 PVS 14s) will be in the $7500Kish range.
In Pure Dedicated systems I agree, the BNVDs are the best developed dual tube systems on the planet. My partner likes the PVS15, I like the BNVD. One advantage of the BNVD is they are available in a variable gain model, the BNVD-G. If you not in a super Hurry there is a new version of the BNVD-G coming out that has a single gain Knob. One other advantage for the BNVD is we build a geometry correction mounting block that will get the BNVDs closer to your eyes, and we can get BNVDs built with whatever tubes you would like!
The arguments for the BEST tube will run hot and heavy but for a dedicated system I would recommend L3 Filmless tubes over the ITT Pinnacle tubes. Low light performance and highlight performance will exceed the ITT tubes. I make this recommendation owning and using both ITT tubed BNVDs and a set of Rock Star Performing PVS 15s with REAL L3 Infinity tubes. I had to prepay and wait months for, the Infinity tubes.
