Night Vision Simulator: See Through Gen 1, Gen 2, Gen 3, Digital and Thermal

Look around a real 360 degree scene through Gen 1, Gen 2+, Gen 3 green and white phosphor tubes, digital night vision and thermal. Turn the moon down from full to overcast, switch on an IR light, compare two devices side by side. Or walk a 3D farm at night and spot the people, hogs and deer hiding in it. Then see the PVS-14, PVS-31, GPNVG-18 and the thermal scopes people buy, with prices.

Quick answer

  • Gen 3 night vision works by starlight alone; Gen 1 needs a bright moon or its IR light, and digital night vision leans on IR once the moon is down.
  • White phosphor and green phosphor tubes resolve about the same detail. White reads like a black and white photo, green is the classic look.
  • Thermal sees heat, not light, so it works in total darkness and finds a person behind thin brush, but it cannot read a face, a sign or a trail.

Look through night vision: pick a generation and a light level

Drag the view to look all the way around. Pick a device, then turn the moon down and watch what each generation can still see. Compare two side by side with the split line.

Red dots, holos and IR lasers that work with night vision

A tube looks straight through your red dot, so the dot has to go dim enough. These are the optics people run behind night vision, how many night vision settings each has, and what it looks like.

  • Red dot · 4 NV settings

    Aimpoint Micro T-2

    4 night vision settings. The small, tough dot most helmet NV users end up with.

  • Red dot · 4 NV settings

    Aimpoint CompM5

    4 night vision settings, AAA battery, the Army's current M68 family.

Dog or coyote on thermal?

Hunters admit they mix them up. Two animals at the pixel count a real thermal sensor puts on them: pick the range and the sensor, then pick the coyote.

Night vision comparisons

How the night vision simulator works

Every scene is a real 360 degree photo. Daytime photos are darkened to the light level you pick, with the sky dimmed and stars added, then each device is drawn on top: how much light it gathers, how sharp it is, how much it sparkles when light runs short, how big the halo is around a bright light and what colour the screen is.

Tubes and night vision cameras see near infrared as well as visible light, and leaves reflect a lot of it, which is why trees glow under night vision. The simulator brightens foliage the same way. Thermal is drawn from what each surface usually does after dark: sky is cold, road and stone hold the day's heat, leaves run cooler and people are the hottest thing in the frame.

The 3D walk uses the same device model on a rendered farm: moonlight, sky glow and the yard lamps are lit in real lux, the IR illuminator is its own light only tubes and cameras see, and thermal reads a heat value per surface that fades with distance.

It is an illustration, built so the differences between generations are easy to see. Real tubes vary unit to unit, and a photo never matches a dark adapted eye. Use it to decide which class fits your night, then judge a specific device by its spec sheet: resolution, signal to noise and figure of merit.

Frequently Asked Questions

What is the difference between Gen 1, Gen 2 and Gen 3 night vision?

How much light the tube gathers and how sharp it is. Gen 1 is a simple amplifier: bright in the middle, soft at the edges, and it needs a bright moon or its IR light. Gen 2 adds a microchannel plate, so it is sharp edge to edge and usable under a quarter moon. Gen 3 adds a gallium arsenide photocathode that gathers far more light, which is what makes starlight alone enough.

Is white phosphor better than green phosphor?

Not sharper, just different. Both use the same Gen 3 tube class and resolve about the same detail. White phosphor reads like a black and white photo; green is the classic look and usually costs a little less. Users are split on which is easier on the eyes, so try both if you can.

Can night vision see in total darkness?

No. Tubes and digital night vision amplify light that is already there, mostly starlight, moonlight and sky glow. In a closed room or deep woods on an overcast night they need an infrared illuminator. Thermal is the one that works in total darkness, because it sees heat, not light.

Is thermal better than night vision?

For finding a warm target, yes: a person or animal glows against cold ground and leaves. For moving around, reading terrain and identifying who you are looking at, night vision wins, because thermal shows no texture, faces or text. Many hunters scan with thermal and confirm with night vision.

Is digital night vision worth it?

For a hog or coyote rifle on a budget, often yes. A digital scope costs a fraction of a tube and records video, but it relies on its IR light once the moon is down and the image is grainier and laggier than Gen 3. It is not a head mounted device for walking around.

Why do trees glow under night vision?

Leaves reflect a lot of near infrared light, and night vision tubes and cameras are sensitive to it. Grass and trees come out brighter than they look to the eye, which helps a person in dark clothing stand out against them.

Can I walk around in night vision?

Yes. Pick Walk in 3D above the view: a farm at the edge of a forest with four people, three hogs, a deer and a coyote out there between 70 and 230 metres away. Walk with W A S D or the arrows, switch devices as you go and tap anyone you spot. Hogs are dark shapes under night vision and glow on thermal, which is the whole argument for thermal on a hog rifle. Pick Your street to walk your own road on Google Street View with the same night vision look laid over it.

How accurate is this simulator?

It is an illustration built on real 360 degree photos and typical published device specs. The gaps between generations are what it is for: light gathering, sharpness, sparkle and halos. Real tubes vary unit to unit, so judge a specific device by its spec sheet.
