What Are Night Vision Binoculars
Night vision binoculars are an amazing tool for seeing distant objects at night. Even in pitch black, a good night vision aid can allow a person to view people, animals, or locations with an impressive level of clarity. People in many professions use night vision technology as part of their job. So, what are night vision binoculars?
How Do Night Vision Binoculars Work?
Night vision binoculars are exactly what they sound like: binoculars that allow vision in conditions with very little light. To accomplish this, these special binoculars use a number of interesting pieces of technology.
In night vision hardware, the photo-cathode is the operative hardware that allows detection of very small amounts of light. When the world looks pitch black to a person, there are actually still small numbers of photons traveling through the air. Our eyes are just not sensitive enough to pick them up and interpret them as visible light. When photons enter night vision binoculars, they strike the photo-cathode, which produces an electron for each photon it detects.
These electrons are channeled into a photo-multiplier, which multiplies the number of electrons it recieves. These takes a weak signal and amplifies it, allowing just a small number of photons to produce a large burst of electrons.
Once the electrons have been multiplied, they are used by a phosphor screen, which creates an image based on the electrons it receives. This is the same technology used in the first television screens.
When the viewer looks at the phosphor screen, they see an image produced by amplifying the signal of the original photons, allowing there to be enough light to make out images in otherwise pitch black conditions. This image comes out green, because when the photons are converted to electrons, the data of their wavelength is lost. Color is determined by wavelength, so when the electrons are converted back into light, the light is all the same green color that is produced by the phosphor screen.
All night vision technology works this way, but night vision binoculars are special in that they can see distant objects. The lenses in the binoculars focus the photons as they would normally, and it is this focused image that is amplified. Thus, with night vision binoculars, even far away dark objects can be seen clearly.
So, what are night vision binoculars good for? There are a number of common applications. Obviously, the military and police have good applications for seeing activity in the dark. Sailors who need to travel at night also need a way to navigate and avoid collisions with rocks. Some birds only come out at night, so dedicated bird watchers will often use night vision technology to see them.
These are just a few uses for night vision binoculars. This amazing technology can be used any time anyone needs to see at night, so the uses are really only limited by the imagination. Night vision binoculars use incredible technology to amplify available light, allowing stealthy and reliable vision at night.
