The 50 degree setup looks pretty good.  Is there any degradation of image with it around the edges or is it as good as the current setups?

Very interesting, so you could take any night vision with PVS14 optics and swap or just build from the start with these 50 degree lenses.  Would the cost for the 50 degree lenses be notably more?

I'm excited for these. I probably won't have the money required to buy them for a while but I'd love to squeeze some more FOV out of my pvs-14, especially if the performance hits with previously available models of expanded eye relief lenses

These would work with any dual setup that uses -14 tubes right? So Katanas, RNVG, etc?

@Lowdown Do you plan on offering an upgrade service? Do you think it's worth the ~2k cost for binos or are you reserving judgement until you've spent more time with them?

It should be <$1k for a pair of objective lenses, so not $2k.

I think it could absolutely be worth it to squeeze more performance out of a dual housing especially since standard Carson glass is ~$700 IIRC - but having seen a lot of different lens coatings and whatnot I'm not gonna be the first in line.

I thought that cost estimate was for an objective lens and an ocular lens; i.e. for one tube?

This is turning out ot be a pretty cool year for Night Vision.

This might be the most exciting SHOT Show for Night Vision I can remember in a long time.

With the VCSELs the 50 degree lenses, all the new aluminium ruggedized housings and I don't know if you guys saw the new adjustable low stow aluminum J-Arms or Nocturn Industries new low pro mount that looks like it can give the Wlicox's a run for their money.

I gotta say, I'm pretty pleased with everything I've ben seeing. I think the civilian night vision world is going to really go strong this year.  Hopefully, we'll see more and more guys getting into night vision for MILSIM, hunting, and training.  I bet the night vision training guys are seeing their 2024 classes filling up fast this year.   Now, if we can just get some civilian ranges that would cater to night vision guys. Love for it to be the norm that every bro had at least a PVS14.

I stand corrected on the pricing - I understood it as just the objectives. Does the system require both to work properly?

So if I had purchased the BNVD with photonis tubes from you, the cost to get 50 degree field of view would be approx $2000?
Really interested in these!!

You should be able to sell your old lenses and recover 1/3 of the cost or so.

Not a bad idea.
Things like that probably shouldn't end up rolling around my parts bin haha.

I would be interested to look thru these, I had a set of the agm 50 degree binos. I liked them except the horrible flare from any light source. I really should get another set of binos, but they dont do much for me. I actually put a wp in the left eye and a gp in the right, i could not tell. My brain just kind of ignores my left eye.

Excellent feedback so far, thank you. How was eye relief compared to Carson glass?
Link Posted: 2/25/2024 11:01:27 PM EDT

My god!
That's a drastic amount more to see IMO.
Is the image clear to the edges like the regular ones?

Curious on eye relief and eyebox as well, it'd make or break the design.

Robert,

Awesome pics bud.  Thank you.

Is there any noticeable fisheye/distortion in the boomslang lenses?

This is the single question on all minds. My guess is that there will be some quality sacrifice to provide the wider image. If the sacrifice is not too bad, I'd say it could be worth it.

Let us know!

Does the image get shrunk down as if it were .75x? Or is it just a legitimately larger image,  in the way a large format camera sensor works vs a crop sensor and is still 1x? Hopefully it's clear what I'm asking.

And the milspec is 25mm, right? I run my NODs out at almost full extension on a G69 so curious how that would affect me - but I really like what I'm seeing so far otherwise.

@lowdown
@DR2341

What I think he means, does it look like looking thru a 4 power scope with a 100' FOV, then zooming back to 3 power with a 125'fov. More field of view but objects look smaller.

As someone who had the agm50's, no there was no difference in size of objects. The difference is just the angle of light admitted to the front and the angle of light sent out the back. Thats why it needs to be both lenses swapped not one or the other they work together.

The one "flaw" is when you do something like this you loose resolution. 25% wider angle on the lens, 25% reduction in resolution ( not exact math i think ). The explanation, lets make some numbers up. Lets say the front of the tube objective is 20mm, with a resolution of 60 lines per mm ( easy math ) that gives 1200 lines across the entire objective. If that is divided in to a 40 degree fov you get 30 lines per degree. if you then change that to a 50 degree fov you get 24 lines per degree.

This is what I saw with the agm 50's, anything under 50 feet it did not really matter, get out to 100 feet and you could see it. Get out to 200 feet and a 2-3 inch tree could disappear and reappear when I moved my head.  24 lines per 60 min of angle, 2 inches is 2.5 moa roughly at 200 feet, and under 1/2 line per moa ( 24/60=.4 ) add in the crappy agm lenses.  something disappearing over 3 or 4 lines over a spread of 1200 lines is possible. Its like loosing a few pixels on a tv, sure you might notice it on some back grounds but not all.

I think I got the math right above

Yes they where bad with any kind of light source and flair, but with no lights close they where fine. But there was a loss of resolution and your pics of those seem to show it as well. Assuming the pics are accurate.

I would honestly really like going back to 50 degree lenses. It almost makes the idea of a new bino housing with those lenses make sense because I could sell my complete -14 housings with glass. I am running the one pano bridge for 2 -14s right now to have a wider fov

Photonis said they had to sacrifice a little center resolution. In real usage though it's hard to say at this point how much impact that will have.

Might be a dumb question but with all the talk of dualsi is there gonna be any problems running this in a single tube setup?

This looks like a promising upgrade to help bridge the gap between a 14 and dual tubes. I'm not suggesting it as a replacement.

I've always felt like a single tube isn't good enough, but the dual tube cost is hard to swallow for a personally owned device.

I saw that but wondered if it would cause some weird visual effect if only done in one eye. Weren’t they designed to fix visual issues from running duals?  Thought I’d read that somewhere.
