- At Custom Night Vision we collimate every unit that leaves our facility to our standard. We often see binocular units from manufacturers having a sub par standard for collimation. In this video Kevin gives a brief overview of the process here at Custom Night Vision and also touches on a few points to why taking the time to properly collimate is vital to the end user.

I'm really taking a loss here but... I'll trade you a peanut butter and jelly sandwich, a bag of Doritos, and a cool aid pouch for a pair of those goggles. My mom makes the best pb&j sammiches.
😂😂😂
with articulating tubes does the position of the pods effect collimation and if so, would that imply that articulating tubes are only perfectly collimated at 1 point in their travel arc? you have opened up a very deep rabbit hole... lol
Yes, articulation does affect the collimation, however it’s not enough to take them out of spec unless you’re a hammerhead.
@@kevin11288 nope, that's my ex gf's nickname.
Depends on the builder and the housing. A housing with a longer bridge such as DTNVS or 1431 don't shift as much because the angle shift to set IP isn't as big. Much more noticeable on Katana. It also depends on how good the builder is, and whether they collimated close to boresighted. If you have a builder that collimated the tubes to eachother but with a significant offset, you will see much more of this issue. We have discussed this at length with CNV so it should not be an issue with their units.
Do you guys also collimate PVS-14's? Mine works fine on the right eye because my eyes can cross, but doesn't work well on the left because there will be a hight difference in what the 2 eyes see.
How does this process work for pano systems like RPNVS and 2 14s on a panobridge? This is the set up I am interested in. I currently own a 14 I got from KS.
How come I can look through my pano Pvs-14’s without issue? You’d think that would be the most extreme case of miss alignment
Edit: after having looked through miss aligned duals, I can confirm that Collimation is required.
That’s a good question, I will tell you that not everyone can utilize a setup like that without discomfort.
Does collimating apply to a single pvs14 relative to the opposite user’s eye? I have a J arm that articulates from left to right eye. I’ve noticed that when the PVS14 is on my left eye, it has decent image alignment with my naked right eye and feels natural. However, the pvs14 on my dominant right eye makes everything wonky with double vision. Is this normal, and is there a way to adjust this so it more naturally matches my opposite eye WITHOUT making a custom J arm that rotates the monocular just right?
id have to put it on the hoffman and see if the image shift has been offset with the eyepiece.
Can you do this on sayyyyy 2 M2021 housings?
On a PVS-14, am I able to rotate the tube within the housing, so the blem appears in a different location?
Unfortunately not, the tube sits on a small dowel pin to ensure the tube doesn't rotate. The pvs14 requires specific contact points on the tube to provide power.
Hello, I have a 1431 mk2 housing and I don't know if you've seen the new fixed 55 degree panned pods that are coming out soon, made by code 4 defense. I saw some people talking about how these would basically be impossible to collimate. Is that true? I also saw a guy saying you could collimate them on the test set with the stock 40 degree pods and then just install the 55 degree pods. Would this work? Or perhaps there is another solution. Thanks for the videos.
yeah, it would not be possible to collimate them properly. changing the pods would completely negate any collimation done with the previous set. Please tell me who said this. You could probably collimate them by eye but it would never be perfect. however, no paned bino will have even near perfect collimation while they are in the paned position. collimated and panned are in opposition fundamentally.
@@customnightvision Ok thanks for the response. the guy who said that was just some guy on the fb group who "used to build DOD units". but I also asked the code 4 defense guy about collimation and he said quote "it would just have to be done one at a time like with bridged 14's". Which also sounds like it would defeat the purpose of the collimation but what do I know I guess. What would you say about code 4's response? Also, out of curiosity, how are gpnvg's collimated?
Yes 👍🏻👍🏻. Your mileage may always vary… but it ain’t the cnv set. Not the least important video you guys made. And not even a little intlprop hiccup. True Legit.
👍
Do you offer training and support? I am interested
Training for?
How much do you guys charge for collimation service on an existing set of NVGs?
Depends on the device. call us.
When you say “turn the eye piece” do you mean how far onto the unit’s threads the eye piece is screwed? And then once it’s lined up you move the locking ring to hold it there? So on duals the rear optic one one pod might set a little further back or forward on the the threads than the other pod? Am I thinking of this right?
Yes that is correct. if done properly the eyepieces should be pretty level with each other.
Are 3d printed housings in higher tolerances? Like a tanto?
What do you mean?
@@kevin11288 since each housing is a little different, does a 3d printed housing have higher tolerances?
@@Miles_milez i would say they’re a little tighter tbh.
Spent 12 yrs on NVGs and never ever had an aircrew say he had a problem without any having been collimated, surely any double vision or issue can be cleared by near or far focusing, must be as never had an issue
How do you know their devices weren’t collimated?
@@kevin11288 Because I was servicing them
Interesting. And changing the focus would not correct the optical axis offset. Not saying you can’t eyeball it but that’s not the right way to build nightvision.
@@kevin11288 I can confirm this. I've built 12 binoculars so far for friends. Never had any issues. It seems like there is some sort of fishy business going on with night vision vendors.
@@davideinstein7887 how so? This isn’t a process that we just made up. If you don’t want your goggles collimated that’s up to you but we are simply telling people we build ours the right way as is required for aviation use per US milspec. Collimation isn’t a process based on opinion it is rooted in scientific fact.
