Overall, a night vision binocular is grounded on an image intensifier. This intensifier amplifies the feeble moonlight, stars, or external infrared illumination if the observation occurs in absolute darkness. It is called a night vision device vacuum cell. Usually, it's got a cylindrical shape, which comprises an accelerating system of electrodes, a photocathode, and a screen with a phosphor-coat at the other end. This device requires a voltage of several kilovolts to operate, which is summoned thankfully to a high-voltage power supply.
Three things played a significant role in the opportunity to design relatively inexpensive digital binoculars: sensitive matrices, a microelectronic element base, and screens for projecting images (like those that we use in cameras).
Fortunately, you do not need to graduate from any university or shovel gigabytes of information on the Internet to find a good night vision binocular that is right for you. However, it is still worth knowing something about not buying a pig in a poke. As soon as you start digging and learning about binoculars' different technical characteristics, you will suddenly realize that the main emphasis is on electro-optical converters. Here are the essential things to know on this topic:
The gain of the image intensifier. This thing tells the user how many times the device has amplified the light. In the most modest and ordinary devices - 500. In binoculars of a higher class (and, accordingly, more expensive and modern) - 50 thousand. The more, the better, but, as I mentioned above, for the sake of this, be kind enough to uncover your wallet wider.
Image intensifier resolution. This parameter helps to understand how accurately binoculars reproduce images of nearby objects. If you are a physicist and care about things like units of measure, then here they are - lines per millimeter. This figure can reach 65-70, and, of course, this parameter is significant, but you should not overestimate it. Experience and practice show that a resolution of 35-40 l / mm is sufficient for the comfortable use of binoculars.
Integral sensitivity of the photocathode. This is the ratio of the photocurrent to the incident luminous flux from a common light source. In simple words, this thing determines the strength of the current with which the light falls. Again for physics and measurements lovers - it is amperes per watt here. But, to be honest, we shouldn't be interested in this much because this whole story remains invisible to the operator, like infrared light or sound.
Lens size. This is where size matters. The fact is that the larger the diameter of the lens, the better it picks up weak light.
Amplification of the device. Perhaps this is the main thing that should interest the user, be it a hunter, a military man, or an ordinary bird watcher. Through binoculars, you see the image generated by the image intensifier. This is the essential function. Therefore, when choosing binoculars, pay special attention to how the focal lengths of the lens and eyepiece correlate.
The weight. If you have any weight restrictions and every extra gram is crucial to you, the easiest thing to do is to refuse binoculars because they are generally not lightweight. Option two: get the lightest device you can get your hands on. But keep in mind that super-light binoculars are more expensive.

What Are Night Vision Binoculars Good For?
It just so happened that humans are daytime beings. We do most of our business in the light of the sun. And vision is probably the leading and most important sense organ that we use. However, like everything in our body, it has weaknesses and disadvantages. The main one is that we see poorly in the dark. But humanity has never been stopped by any limitations of the organism. Therefore, we managed to level these defects of our vision. Using technical breakthroughs, we have created devices that allow us to see at night and during the day.
We have invented a wide variety of night vision devices: monoculars, scopes, glasses, binoculars. The latter is probably the most popular. Binoculars differ from areas in that we can use them without weapons. Compared to monoculars, binoculars are more convenient. Only glasses can compete with them, but at the same time, they are more expensive. This is a disadvantage of glasses because binoculars can be pretty affordable for the layman.
For a hunter, the quality of equipment plays a decisive role because it directly correlates with the trophies that they can get.
If you are the owner of a smooth-bore weapon and its aiming range is about 80 meters, then it would seem that you need to purchase the I + generation binoculars with image intensifier tubes. However, it was evident that the owners of binoculars who "see" at 300-500 meters will easily overshoot you while hunting, even with the same type of weapon. So think about whether it is worth saving. The more modest the binoculars, the more modest your trophies.
Finally, we will list a few valuable advantages of night vision binoculars:
Waterproof and nitrogen-filled - Most modern models have a waterproof case with a non-slip coating. If you are an avid hunter or a backpacker who likes to sleep in a tent, you need binoculars with a sealed construction and nitrogen filling. Such a device is not afraid of changes in water and temperatures.
Built-in rangefinder. Not all models have this thing, but hunters are advised to buy binoculars with it. It can be assumed that it will be very convenient for you, as a hunter, to know the exact distance to the animal.
Rubber eyecups. These things ensure the correct distance from the eye to the eyepiece. If they were not there, we would experience little pain in our eyes, staring through binoculars for hours.
Photo and video recording - this feature is present in digital models. It gives you the possibility of recording what is happening with the transfer of materials to a phone or tablet via wi-fi.
