- We've had our hands on the Photonis Defense Boomslang optics for awhile now and have been rigorously testing them. In this video Kevin breaks down, all the differences and challenges the optics were designed for. These are now an option on our website for any NVD you should like to build with.

Nice video! As we mentioned on the Cold Harbour video the Boomslangs are designed specifically for the PVS-14. That particular standard housing size (the internal dimensions of the housing) limits what anyone can do in designing wide FOV optics. We can design 50 degrees with 25mm eye relief, it requires a totally different internal housing design from a standard PVS-14. Therefore, the Boomslangs were designed to provide 50 degrees FOV capability that is backward compatible to almost all PVS-14 type night vision goggles currently in use. The end goal was to minimize fisheye distortion prevalent on other wide FOV optics, while preserving as much clarity as possible edge to edge while drastically increasing situational awareness.
Well as I said, it looks like you achieved your goal. you never contacted us about the tubes for testing?
@@customnightvision You have an open invitation to our facility, and we'll contact you when we have the tubes for testing.
@@PhotonisDefenseInc.Would love to see them reviewed. These lenses look spectacular btw! Very well done
Very nice test guys, thanks for the shoutout and great job.
No problem dude.
Any time!
I don’t want to sound too stupid, but I have so much to learn about this stuff. I appreciate the content!
Thats what were here for. the only stupid questions are the ones we dont ask.
@@kevin11288oh cool, hypothetically speaking if I dropped my rnvg's in a Porta potty how water resistant are they and what is the likelihood of pink eye?
we appreciate you watching.
thanks a lot, very informative and valuable. good job
Glad it was helpful!
Thanks man
Thanks Kevin and Ben! I’m expecting my PVS 14 back from you tomorrow with the Boomslang lenses. Amazed at the turnaround time. You guys rock.
K. Keefer
No problem man, we appreciate your business.
What's your take on these lenses? And the eye relief.
Crushing it, once again!
Thanks dude
Thank you.
FOV so hot right now
whomp
Very nice video! Thank you.
Thank you for watching.
We appreciate you.
FYI, if you hold ALT and press 0176 on the number keypad you get the degree symbol °
lol thanks! fixed it 😂
Dannngg tell me about trek lore.
@@customnightvision What?
I definitely need these optics 😊
oh she got a big ass? Nice.
Kevin:
"we decided to use a tube thats...not to high spec!"
also Kevin:
"yea so its an L3 filminess super gain tube..."
LMFAOOO
Hey, it wasn’t 40snr this time
Would you say the Carson/RPO is still a general all around good choice, where as the boomslang seems more specialized for if your really needing that FOV increase?
Yeah man absolutely. these are all trade offs that come at a cost.
Thanks guys
Our pleasure!
@@customnightvisionhow much weight will I be saving with your favorite RPO optics set over my Carson/fuji optics on my DTNVS MG?
Very interested in these. So if I understand you correctly, if I have a spot in zone 2, that spot will be perceived as being larger while viewing thru the lenses?
Yes.
Did you test if that is the resolution limit of the optics, or if it scales up with a higher res tube?
While I had to use a 25mm tube to get a 92° fov, I noticed, that I still got a rather strong magnification on the tube details when looking around in the image.
Also the smallest 25mm tubes I'm aware of, are in 43mm format. Having 36mm tubes with 25mm screen and photocathode would be really nice in my opinion.
But it seems the trend goes towards 16mm screens.
No sir, I tested the one tube as a constant.
@@customnightvision Thanks for replying to my late night ramblings.
Great video! Is it possible to install these onto the RNVG-A? That uses PVS14 tubes but I'm not sure if the Boomslang parts are compatible
Yes they are compatible.
What would the fov be with these optics but on a noisefighter or similar bridge?
10* more left to right. But also up and down and more fill in the center. I find with my rpnvgs I don’t usually run them fully out because I loose too much in the center. This is hopefully going to help with that.
elohel "Ineed 180*"
Can you do a halo / mixed light comparison with the boomslang vs carson? (Just like you did in the video Carson vs RPO) In that video the extra halo effects made the Carson the first choice for me.
Im not really interested in doing anymore boomslang testing.
What kind of FOV performance are you going to see with a set of 65 degree set RPNVGs?
\
Was wondering this too. Guessing probably just a bonus 5° on both sides, along with the extra on top, bottom, and overlap in the center. But I'm regarded so idk.
@@JAD77755 i talked to a buddy who has both. he said lenses on a set of RNVG A's is better than the panning, and there are too many draw backs with both together
yeah id choose one or the other. the RPNVG is kinda heavy and bulky..
Dope. Thanks for the info! Super helpful for a non pro like me. Any idea on price yet?
$1300 upgrade on Binos
Thank you.
I saw the price at cold harbor for the boomslang. What do they do that makes it cost around 150 dollars more than the boomslang on your site? Or what do you guys do to make yours cost 150 dollars less?
The product is the same. I dont know what else to say.
Commentary for that algorithm 🍺
we appreciate it.
Would it have even more benefit with panning night vision unit ? Or is that not how that works lol, could be a dumb question.
No such thing as a dumb question, yeah i mean you would have more fov but the reduced eye box may make it more difficult to utilize it while viewing the tubes off center eyeline.
Would these work with something like the tarsier eclipse? Im assuming no.
yeah they probably would.
Any issues pairing it with a clip on thermal ?
no, seems to work ok.
I hope rpo puts out a lightweight increased fov
You should spam them just for funsies.
Photonis going to release their high gain tubes in white phosphor soon? Seems like that might be a real game changer.
No idea.
Wondering the same. Saw a comment where they said they were switching to 4K in 2024.
I’m still waiting for someone to test these in a pano setup to see what that’s like
I think steele put some in a RPNVG but im not doing that.
Damn they got fov sliders on nods now
lol
Id still rather go with the 58 deg lens with more fov, similar res , higher eye relief and way lower costs
cool. let us know how they work.
@@customnightvision they seem to work pretty well, they have like no distortion and the eye relief is over 20mm so they can be used even with gas masks (youll lose some fov but its still more than 40), the only disadvantage they have is ofc the reduced Resolution and apparently they also seem to have a slightly darker image,but i myself didnt notice that when using them.
For the price there great, and i would even buy them when they would cost more
They are nice. But Resolution is not even close. But at 1x it's the least important spec..
@@aesthetic8780 i mean, its obvious that they have worse res at this fov.. but i think they still do great and i would use them over boomslang lens, just because eye relief and fov increase
@@ID-9999 Have you used boomslang before?
I never knew that it is the optic that limits the FOV. I thought it was the tube. Huh.
Well it kinda does
@@kevin11288 Is the tube the actual limit, but now we are just putting a lens in front of it, that "zooms out" a bit? :)
Its a combination of things. the optics manipulate the light on both sides to create an image that we consider acceptable (similar to what we would see unaided). Te further we move away from that the less usable the image gets for use in the helmet mounted format.
@@customnightvision Ah okay, that makes sense. Thank you, its nice to have content like yours, to "nerd out" about night vision ;)
If my analisys peralisis wasn't bad enough.
Go deep bro.
@@kevin11288 If I go any deeper I'm going to come out the other side.
lol trying my best not to run with this.
These optics are too expensive compared to rpo/carson, if photonis lowers the price 20-25%, I'd consider them.
yeah they are pricy.
YOU SHOULD DO THE FLASHLIGHT POINTING TEST TOO !!!!
Like see how long it takes dad to strike us if we dont hold t steady?
@@kevin11288 lol, nooooo !))))))
elaborate.
