The NVG-ALPHA Omni 7 is the best Night Vision Goggle value with American gen 3 tubes today. Why is this?

The NVG-ALPHA Omni 7 is a binocular night vision device (NVG-ALPHA) that consists of an American 3rd Generation Omni 7 Image Intensifier Tubes, American Mil-Spec Optics by Carson, and a housing designed by OPFOR Canada, then optimized and assembled here in the USA with the best optics available. Carson Optics are the standard to which all others are compared. They are Mil-Spec and a Carson is a primary supplier to all branches of the United States Military.

What do I get with the unit?

Each standard NVG-ALPHA system ships with the goggle, lens covers, AA batteries, and soft case. A 5 year warranty against system failure during normal use is included. All Adams Industries systems ship within the USA for free.

What are the Omni 7 Image Intensifier Specs?

These were the contract min/max specs at the time of the Omni 7 Contract:

Resolution Ip/mm (min) 64
Signal to Noise Ratio - S/N (min) 28
Photocathode Sensitivity in uA/lm@2856K (min) 2,200
Sensitivity in uA/lm@880nm (min) 120
Gain fL/fc (range) 50,000-80,000
MTF@2.5lp/mm (min) 0.92
MTF@7.5lp/mm (min) 0.8
MTF@15/p/mm (min) 0.61
MTF@25lp/mm (min) 0.38
Halo in mm (max) 0.70
Phosphor Type P-43
EBI x10^-11 (max) 3

*These are the contract minimum specs at the time of the Omni 7 Contract. These are the minimums & maximums from the contract and reside in the public domain.

So what does this mean?

Let's tackle where the Omni 7 stands compared to other options. The two specifications most often compared are the Figure of Merit (FOM), and the Resolution. FOM was not a requirement in the Omni 7 specs. However, we can calculate it by multiplying the Resolution by the Signal to Noise Ratio. For the Omni 7, this is 64 lp/mm x 28 = 1792. Let's compare with the alternatives out there:

Omni 7 (min) 1792

Omni 8 (min) 1625
Elbit XLSH (min) 1344
Elbit SLH (min) 1536
Elbit YH (min) 1600
Elbit VH (min) 1792
L3 18UM (min) 1542
L3 20UM/UA (min) 1792
L3 22UM/UA (min) 1920
L3 24UA (min) 2160

Granted, very few tubes will ever actually test at the minimum spec, but allowing this as a starting point makes you realize that the Omni 7 starts the race ahead of tubes that sell for much more money. Not that there are not reasons to seriously investigate these other options; just that the Omni 7 should usually be considered a valid competitor.

*What do all those "tube specification" numbers mean?

Obviously some of you are going to want to understand what it is we are using to try and sell you on one product versus another. We understand this and hope that the following assists you:

Resolution in Ip/mm: This is just another way of saying how fine the picture is. Just like your TV in Megapixels, as the number increases, this is good.
Signal to Noise Ratio: If you've heard this term, it likely had something to do with radios. Higher SNR means less static. Just think of visual static and you have it.
Photocathode Sensitivity in uA/lm@2856K: This is the ability of the tube to change photons (what we see) into electrons. The higher the transference, the more electrons there are to photo-multiply.
Sensitivity in uA/lm@880nm: Another measure of of sensitivity but this time particular to a wavelength of light in the Near IR spectrum.
Gain fL/fc (range) 50,000-80,000: You may have heard this expressed as "times." Yes, this is how many times the tube multiplies the number of electrons.
MTF@2.5lp/mm (min)
MTF@7.5lp/mm (min) Modulation Transfer Function: This measures how well the resolution and contrast of the system work together to deliver contrast.
MTF@15/p/mm (min)
MTF@25lp/mm (min)
Halo in mm: That glow around a light that you see when you're tired is basically biological HALO. The higher the number, the more a light is obscured by its own glow.
Phosphor Type: P-43 is modern green phosphor, P-45 is white phosphor, P-22 is green phosphor used in old American systems and some foreign systems (same difference).
EBI x10^-11: Equivalent Background Illumination. Think of this as the glow that your night vision tube just makes on its own. Now think of it as an EVIL glow. Less evil is better.

FEATURES

The NVG-ALPHA is a tested mule of a housing that accepts very commonly distributed PVS-14 optics. Do not be stuck with an unfixable goggle in the event of an infrastructure failure or get told you'll have to wait months to replace proprietary components.
Water resistant to 5 feet (154.2 cm) for one hour.
Tube performance where it really counts:
- Minimum Figure of Merit (FOM): 1792
- Resolution Ip/mm (min) 64
- Signal to Noise Ratio - S/N (min) 28
- Photocathode Sensitivity in uA/lm@2856K (min) 2,200
