L3Harris AN/PVS-31a
The L3Harris AN/PVS-31A is an extremely light weight binocular night vision goggle. The PVS-31A was designed by L3 in conjunction with USSOCOM to replace the PVS-15. The unit features an articulating housing with manual gain, a battery pack, and incredible tube resolution.
The PVS-31 can be run both off of an onboard AA battery or powered from the included battery pack. Because of the light weight design, the user does not need to run a counterweight and can simply use the battery pack to balance the helmet. The PVS-31 battery pack also has an on board IR strobe for signaling and aerial identification. The IR strobe is operated by a single switch on the back of the battery pack. One great thing about the ability to run a battery pack is the speed in which the goggles can be up and running. With the PVS-31 the user simply can drop the dovetail on a Wilcox G24 mount and plug in the battery cable to the battery pack port on the PVS-31 housing and use their goggles.
The AN/PVS-31A has an articulating housing with independently rotating optical pods. This lets the user deploy both tubes or a single tube. This is especially helpful when users are deploying their PVS-31’s while using a thermal device. The optical pod articulation also lets users stow their goggles without having to flip the goggles up on the helmet mount. This reduces snag hazard and additional height added to the helmet.
Tube Specs
The AN/PVS-31A uses L3Harris Unfilmed White Phosphor autogated image intensifier tubes with a 2376 min FOM rating from the factory. These unfilmed tubes provide incredible clarity, low light and high light performance, and increased depth perception. These are L3’s most advanced intensifier tubes and offers significant performance increases over other white phosphor systems.
2376 minimum FOM Unfilmed White Phosphor:
- FOM: 2376 minimum
- Milspec Spot Spec: can have max 4 spots per tube larger than .003″, no spots larger than .003″ in zone 1. Spots </= .003″ are acceptable.
- This option is how they ship standard from L3Harris.
2376 minimum FOM Unfilmed White Phosphor – Aviation Grade:
- FOM: 2376 minimum
- Aviation Spot Spec: Max 3 spots per tube larger than .003″ in zone 3, no spots larger than .003″ in zone 1 or 2. Spots </= .003″ are acceptable.
- This option is for our customers that want a stricter spot spec offered from the factory. This option is hand selected strictly to meet the above aviation spot spec. Even though PVS-31a’s in general have incredible tubes, spots are still a reality in all night vision. If you are a customer that wants to insure a stricter spot spec this is a great option. Please understand that although an aviation spot spec is way stricter than the milspec spot spec, spots </= .003″ are still acceptable and are a reality of night vision.
- Please allow for additional lead time for aviation grade as this is a stricter spot spec than offered from L3Harris. Since we cannot order these to an aviation spot spec from L3Harris we cannot quote a definitive lead time. On average this option takes 30-60 days longer than the standard option.

I started off calling and talking to Licentia Arms about different goggle options. I was already leaning towards 31s. After talking I decided it was definitely what I wanted.
I got the aviation grade and when they were delivered, they were amazing! I’ve been using them for a couple months now and I’ve been really happy. The goggles have no blems and the FOM is great. Super clean goggles.
Licentia was great throughout the entire process. Before ordering, waiting for my order, and after it was delivered. I’d order again.

Order PVS-31a’s through Licentia Arms and had a great experience. They were helpful with my questions and shipped my orders all together like I asked.
The 31a’s are phenomenal and a huge upgrade to my WP PVS-14.
Great people and company and would absolutely purchase from them again.

These are an absolutely PHENOMENAL product! After spending almost $14K for a set of goggles I was hoping they would be as good as I was told they would be and they were in fact better. Crystal clear. Extremely clean image with no spots. I couldn’t be happier.
I can’t speak highly enough about this company. Like many of you I spent almost a year researching night vision to make sure I was getting something that would suit my needs. In the course of my research I called Licentia to ask a question. Robert (the owner) talked to me for more than an hour and provided me with tons of information on the specific products they offer. If you’re considering purchasing any sort of night vision talk to Licentia – they are a goldmine of information and will make sure you’re making an informed decision.

These guys know their stuff extremely knowledgeable and willing to direct you in the right direction to fit your operating parameters. One of the best customers service experiences I have had in awhile. These PVS-31a’s are top of the line extremely good image quality. Everyone I let try them has the same reaction “Holy f$&k I knew they would be good but not that good”.

10/10 would recommend buying the aviation grade PVS-31s from Licentia Arms. Robert (the owner) is extremely knowledgeable and was happy to answer my questions and help me figure out exactly what product/spec would meet my needs. He really under-promised and over-delivered on the specs too (they promised over 2376+ FOM, actual for mine was 2600+) so overall extremely satisfied with my purchase and would buy from them again.

Amazing quality product as to be expected with L3 Harris factory SEALED products. (Note- I haven’t seen other vendors on-line or in person make a point of offering L3 products FACTORY SEALED.)
Amazing transparency from Licentia! Owner spent over an hour with me reviewing data sheets of every pair of 31’s IN STOCK, and let me hand pick my goggles from IN STOCK inventory. When other sites and vendors wanted me to wait weeks or months, Licentia got my product in the mail SAME DAY! I ordered on Friday, and had 31’s in hand WEDNESDAY MORNING! Excellent service, communication, and follow thru! I’ll refer friends and enemies to Licentia!

Very impressed with the set of 31’s James got me set up with. From the call, to choosing specs, to shipping I was very impressed with the professionalism and desire to get me set up with a set of goggles that fit my needs. Will definitely continue to do business here for anything night vision related!

I couldn’t recommend Licentia Arms enough. Purchased my -31s during the Black Friday sale. Robert was great during the purchase process answering any questions. -31s showed up well packaged and sealed. Will definitely use them again for any future NV related purchases!
