Interesting Facts About Night Vision Goggles

Night Vision technology has made visibility possible in almost complete darkness.These technologies often are used by the military and police forces.However, did you know the night vision technology can be used in the civilian world as well? Yes the night vision goggles and other devices have become available for civilians today.

Let us have a look at some of the interesting facts about night vision goggles and other NV devices below.

  • Who Invented Night Vision Devices?


The German Army is believed to be the first people to introduce night vision devices on the battle fields. These devices were first produced by them in the mid 1930s. However, until the mid 1940s the first Panther tanks used them in action. These night vision devices are referred as Generation 0. Besides that there were many infantrymen who used Sturmgewehr 44 assault rifles with mounted night vision devices. However, it was not a practical usage of NV devices due to the huge batteries mounted on the back of soldiers.

  • Who Created The First Commercial NV Device?

The first ever commercial night vision device was designed and created by Dr. Vladimir K. Zworykin who was working for Radio Corporation of America during that time. Although the device are created with the intention to be used by civilians, it was not a commercial accomplishment due to its size.

  • What Technologies are Used in NVGs?

Typically three different types of technologies are used in night vision goggles. The first one is image intensification, the second is thermal imaging and the last one is active illumination.

  1. Image intensification, is a technology that intensifies the available light for producing a clear image.
  2. Thermal imaging is a technology that helps in measuring the heat difference between the object and its environment for producing an image.
  3. Active illumination helps in combining image intensification technology with an active source of illumination in the near infrared band.
  • Why The NVGs Have Green Display?


You might have noticed that the NVGs have green display. Wondering why green? It isn't any arbitrary choice of color, rather our eyes are more sensitive to the green color. Sensitive here implies that our eyes detect this color naturally making it easier for picking out shapes in the complete dark. In a nutshell, it can be said that green color is easy on our eyes.

  • How do Night Vision Goggles work?

The night vision goggles detect low levels of light and amplify them for better vision during the dark times like nights. Talking scientifically, when the dim light enters the night vision goggles, it hits an internal layer known as the photocathode that releases electrons. These emitted electrons when hit the second layer known as the micro-channel plate, get multiplied before hitting the third layer known as the phosphor screen. Once the electrons pass through the third layer, they get converted back into light which are amplified. The more electrons the device produces, the higher is the image quality.

  • Which NVGs are Best?


PVS7 Night Vision Goggles are considered as one of the best NV devices due to their exceptional performance and reliability. PVS7 night vision goggles are great for people who are scouting around for animals, stargazing, and UFO watching.  These devices are also great for home security and hunting.
