Buying Night Vision Binoculars – A Comprehensive Yet Brief Guide

Thinking to buy night vision binoculars? Before you make the purchase have a look at the following post that is a comprehensive yet brief guide to all your queries related to the night vision binoculars.

The Science Behind Night Vision Binoculars


When a dim light at night enters the lens at the front, it strikes a light-sensitive surface called the photocathode. A photocathode is an extremely precise solar panel that converts photons into electrons. The hence converted electrons are then amplified by a photo multiplier (a photoelectric cell). The electrons leaving the photomultiplier now hit a phosphor screen which is a screen that resembles the screen of an old-model TV. When the electron hits the phosphor tiny flashes of light get created. As a large number of photons originally entered the binoculars, a much brighter version of the original scene gets created over the screen.

Technology that Backs Night Vision Binoculars


For night vision binoculars to work, the image enhancing photocathode and photomultiplier represent the main part of a more complex optical system. The system comprises of a lens closest to the object you are aiming at, a focusing mechanism, the image intensifier unit, a collimator for narrowing and ablaze the light ray passing through it, mirrors, eyepiece, a voltage regulator and battery pack.

What makes everything look green through the Night Devices?

The photons hitting at the front of night vision binoculars carry all colors even at night, but when these get converted to electrons the colored light turns into black and white. However, the phosphors on the screens are intentionally chosen to make green pictures as our eyes are more sensitive to green light. Also looking at green screens for longer period is comfortable than looking at the black and white ones.


Now that you know the science and technology behind the operation of night vision binoculars, it’s time to know how to choose the right device for you. Check out the following tips for more information.
  • Consider the Environment
When choosing your night vision device make sure to consider the environment you will be in as well as the purpose of night time viewing. As far as environment and purpose is concerned the first factor to look upon is the distance as binoculars have different distances. For instance, if you are looking for a binocular to just view things that are fairly close then you need not have to spend extra on the gear that is meant for longer distance views. Also, weather is another factor that affects the light levels and visibility. The binoculars that are powerful are more expensive as well! So choose wisely.
  • Gain
Gain is the relative level of light that you can see through the device. The greater the magnification of lenses, the worse gain you will have. Hence, if your purpose for buying binoculars is night time hunting, then make sure to buy high gain binoculars with powerful technology.
  • Quality of Image
The quality of image also plays a vital role in determining the efficiency of the night vision binocular. However, the better the image quality, the higher will be the cost. That is why; you must realize your purpose, gain level and the environment before choosing the device.
