Honestly, I've never seen this before! Unusual design.

First i was thinking it is a PSQ 20 by ITT
but it seems not.

SENVG stands for Spiral Enhanced Night Vision Goggle - it's a successor of AN/PSQ-20 ENVG, a sensor fused goggle with thermal imagery overlay. It also has all the fancy bits like t/r of realtime video or GPS information, as well as peer-to-peer sharing. It's currently tested at ARMY's testing center at Ft. Benning and the results look very promising - it's much lighter than the quite hated PSQ-20.

TMNVG stands for Tactical Mobility Night Vision Goggle, it looks like a successor of the PVS-14 as the objective lens doesn't look as being made of germanium.

The lens on the SENVG is interesting. There is only one lens (that I can see) but we are dealing with two wavelenghts that have different optical properties. Maybe they are using SWIR? One set of optics would reduce the weight and bulk.

Do you have a picture to confirm that the SENVG only have one lens?

It would have to be swir. Long or mid wave infrared can't pass through glass. That is, unless this material isn't glass based. If it's plastic, it can still pass optical and a very weak signature of long and medium wave infrared. Short wave can pass well through glass or plastic lenses.

I'm not positive about the line where visible light stops, and IR light begins. It appears that near infrared is some sort of visible gray area where human eyes can't see very well but intensifier's see very well. It would imagine then that with a plastic lens or optical lens, this could see into swir, but only with plastic could it see into medium to longwave. This device looks to be a bit small to be capable of housing both an intensifier and a thermal core. If it does, then it's an engineering marvel!

U.S. Army Awards Enhanced NVG Contracts to ITT, DRS and L-3

The U.S. Army Research Development and Engineering Command (REDCOM) have ordered 660 Enhanced Night Vision Goggles (ENVG) from three manufacturers for testing, toward massive fielding of new ENVGs in upcoming years. The awarded companies are ITT, L-3 Insight Technology and DRS Systems. The three contracts, each valued around US$250 million, cover the delivery of the 220 systems in the base year, (2010) and options for the delivery of production quantities in the years 2011-2013. The Army is expecting to field new and improved digital fused imaging goggles by 2014.

Sofar ITT has been producing the Army’s first generation AN/PSQ-20 ENVG under a sole source indefinite-delivery, indefinite-quantity (IDIQ) contract worth about $560 million. This contract expires by the end of 2010. ITT has already provided over 2,400 ENVG systems with another 6,500 to be delivered on the current contract.

The development of the ENVG began in the year 2000. First models were fielded in 2008 with special operations units. By early 2009 the 10th Mountain Division was the first regular Army unit to receive few hundred items. The recent follow-on contracts address an ENVG follow-on program, with ITT has addressed with an updated version of the current ENVG system, called ‘Spiral Enhanced Night Vision Goggle’ (SENVG). This new device is designed to meet high volume production rates and the critical performance requirements of the ground-based soldier.

The SENVG incorporates the 18 mm image intensifier tube and a display beam combiner assembly (DBCA) utilizing an OLED-XL microdisplay produced by eMagin. The SENVG utilizes several qualified ENVG subassemblies and is powered by three AA batteries, which reduces the logistics burden and gives the customer an estimated $130 million savings over the product’s life cycle. Through various system enhancements the SENVG has a digital upgrade capability that will allow the goggle to export fused imagery for transmission via battlefield networks.

Since the fielding of the ENVG PEO Soldier has been delivering ENVGs and in parallel, developing a lighter, more rugged digital system (ENVG-D), that will also support image transfer and display of images from other sensors and sights, Digital Video Recorders (DVR) and remote computing devices. The current systems are significantly more expensive and heavier, compared to the systems they are intended to replace – PVS-7 and PVS-14. The new ENVG (D) is expected to overcome these weaknesses and meet the Army’s objective weight and cost requirements.

eMagin makes 3D personal viewer glasses so the screen is probably very high quality.

Interesting to see the DRS company being involved - could be an additional vendor to the ITT vs Litton race that has been running for years?
Anyway, I think this SENVG will be very widespread in few years - just like today the PVS-14 is.

DRS technologies is a BIG govt contractor, similar to General Dynamics and Raytheon Corp. DRS provides the latest family of AN/PAS-13(V) Thermal Weapon Sights II, M1A2 SEP 2nd Generation Thermal Imaging System, and thermal Driver's Vision Enhancer (DVE) for most wheeled and tracked vehicles. I think the real feud will be between Raytheon and DRS tech. Vehicle-borne systems bring more money, and there are A LOT of DVEs out there getting shot-up, which = Concurrent Logistic $pare$ resupply; very lucrative contract!

Well, that concludes it. Dual lens.

Looks quite lightweight.

Thanks for sharing :) .

Only now we can see that we were actually looking at the ocular lens of the thing thinking how the hell can they make both bands pass the same glass? :)
Good video, thanks

Finally some update to this topic.

1) The TMNVG is now called iAware TMNVG and is aimed for export to friendly militaries
Image

2) The SENVG is now called iAware Fusion
Image

3) both use 18mm tubes, not 16mm as I have expected
