Military night vision goggles can be used by non-military or off-duty military personnel for recreational purposes. Military night vision goggles are ideally suited for hiking, camping, and boating at night. Military night vision goggles were first introduced in the United States in the 1960s.

Since the 1960s, night vision equipment has improved greatly. It still, however, functions according to the same basic principles. All night vision optics are powered by the interplay of four simple features: the lens, the image intensifier tube, the eye piece, and the power supply.

How Military Night Vision Goggles Work

Light enters into the lens. Now, this isn't light as we traditionally think of it. Light, it seems, comes in a variety of wavelengths and a variety of types. Some light is invisible to the human eye, but it can still work for your NV equipment. That's why so many goggles come with an infrared beam. Should you find yourself in a situation where there is absolutely no available natural light, you can turn on your infrared to power your goggles.

The intensifier tube is where the magic happens. In the tube, the photons from the available light are processed chemically and electrically to become electrons. These electrons are then sped up and multiplied, and eventually, hurled against a phosphorus screen. How do you view the images on this screen? Through the eye pieces in your goggles. The fourth component, the power supply, simply makes all these processes possible.
