Best Night Vision Binoculars Buying Guide 2020
A dim light from a night scene enters the lens at the front. This light is made of photons of all colors. As these particles of light enter the binoculars, they strike a light-sensitive surface called a photocathode, which is a bit like a very precise solar panel and has a job of converting photons into electrons. These electrons are amplified by a photomultiplier, which is a type of photoelectric cell. Each electron entering the photomultiplier results in many more electrons leaving it. The electrons leaving the photomultiplier hit a phosphor screen, similar to the screen in an old-fashioned television. As this electron hits the phosphor, they create tiny flashes of light. Since there are many more photons than originally entered the binoculars, the screen makes a much brighter version of the original scene.
For the full night vision binoculars to work, the image-boosting photocathode and photomultiplier represent the central part of a more complex optical system. It includes the lens closest to the object you’re looking at, a focusing mechanism, the image intensifier unit, a collimator that narrows and alights the light ray passing through it, mirrors, eyepiece, and a voltage regulator and battery pack.
Why Does Everything Look Green Through Night Devices?
The photons that hit the lens at the front of night vision binoculars carry light or all colors, even at night. But when photons are converted back to electrons, there’s no way to preserve that information. Effectively, the colored light is turned into black and white. But when wearing night binoculars, why don’t we see black and white?
This is because the phosphors on the screens are deliberately chosen to make green pictures, with the reason that our eyes are more sensitive to green light. And it is also easier to look at green screens for longer periods than to look at black and white ones.Environment
You should always consider the environment you will be in. This reason along with the purpose of your night time viewing are important factors in choosing the binoculars for you. The first thing to consider is the distance, since binoculars have different distances. If your purpose is to see only things that are fairly close, then there’s no need to spend extra money on gear that can see over longer distances. The next thing to consider also is the weather, which affects light levels and visibility as some night vision binoculars are more powerful than others (and more expensive).
Another thing to consider when choosing a night vision binoculars is the gain. It is the relative level of light that you see when looking through the device. Keep in mind that the greater the magnification of lenses, the worse gain you will have, and the need to use more expensive technology. If your purpose for using binoculars is for hunting, it is best if you consider getting high gain binoculars.
This is also one of the most important factors to consider before purchasing a night vision binocular. But the thing is, the better the image quality you want, the higher the cost. That is why it’s very important that you know the gain level and the environment or climate that you will be in. It is important that you should choose the application before the device because it makes no sense to waste money on something you don’t need.
