Cats do not miss, thanks to their ocular systems, any detail of the nightlife. They can clearly distinguish a shape, an object or an animal in the heart of the darkness and it seems like cats are using the best night vision binoculars.
For us humans, things are very different! Once the light is out, the dark does not allow us to see anything, even if the night does not fail to offer us beautiful shows!
Night vision responds to the know-how of various observing system specialists who have put together a way to push the boundaries of human vision. Without going into technical details (no need to flee), remember that night vision devices can boost the brightness so that the night is no longer a handicap. The image observed with the night vision device is “passed through” a specific amplifier that can send back to the eye an image usually the green light to distinguish the slightest detail!
Although night vision binoculars are very easy to use, the technical jargon makes their operation challenging to understand. You will find on this blog all the necessary information to help you make your choice: technical explanations on the action or the different generations, as well as tests of different monocular or binoculars of night vision, but also aids for the adjustment and the interview.
Even though any night vision device will significantly enhance your ability to see the night, there are different generations (from the simple Gen 1 monocular to the advanced military generation 4, plus thermal technology) and different types of night vision goggles Or thermal imaging binoculars (binoculars, monocular, riflescopes) that will give different levels of performance.
After being impressed by their performances and the possibilities they offer, you are probably wondering what the best night vision binoculars are.
I’m here to help you compare and guide you in your purchase by providing you with information and useful tips to choose the product that will meet your needs and expectations. Now you can find cheap night vision binoculars.
What Is A Night Vision Binocular?
It is a night vision device, an optical instrument that can produce images in light levels approaching total darkness. They are most often used by security agencies but are available to civilian users. It is particularly interesting to observe the wildlife at night, but also the starry sky. The term generally refers to an apparatus comprising an intensifying light tube, a watertight protective case and sometimes a fastening system, an infrared illuminator or a zoom lens.
Night vision devices were used for the first time during the Second World War and more widely during the Vietnam War. Technology has evolved a lot since their introduction, leading to several “generations” of night vision equipment with increased performance. Suddenly, the price of first-generation devices has dropped.
Why Use Night Vision?
The night vision devices allow to take part in night activities, to be able to benefit from an apparent luminosity, even if the moon illuminates only very little the horizon!
The primary uses of night vision are:
- Camping and excursions in nature far from the hustle and bustle of the city.
- The observation of wildlife, a hobby closer to nature that is not lacking in followers!
- Navigation in the middle of the night.
- Speleology, although it is most often necessary to add an infrared illuminator, since one moves here, in total darkness.
- The observation of the UFOs, not aliens, but various manifestations in the sky.
- The surveillance of buildings, properties, whether in a private or professional sphere!
The Generations Of Night Vision Binoculars
The main difference between the four generations of night vision is the technology of the amplifier.
Generation I devices use an intensifier tube that amplifies ambient light by accelerating electrons that strike a phosphor surface such as a television. The brightness boost is about 1000x.
The generations II add a micro-channel plate which multiplies the number of electrons before they impinge on the fluorescent screen, thereby increasing the gain up to 20 000x.
Generation III binoculars also add a photocathode of gallium arsenide that creates many more photoelectrons. We obtain performances from 30,000x to 50,000x.
Generation IV further improves the performance.
The modern Generation night vision binoculars provide sufficient light amplification for most recreational activities: nature watching, camping, hiking, fishing, boating; and for many professional uses such as surveillance.
Technical characteristics of a night vision binocular
Course, generation 3 products are more efficient than one e generation. For recreational use (nature watching, camping, hiking, fishing, boating), generation 1-night vision binoculars offer sufficient light amplification at the short and medium range. But they will be less effective beyond 200m.
On these devices, magnification is usually low (compared to conventional binoculars). They are used more for night detection and movement than for observation of details. But with digital cameras and their digital zoom (in addition to the optical zoom), you can now find zooms up to x20.
Weight and Size:
This is a data to take into account depending on the desired use. If a stationary activity can authorize a big box, it is better to privilege the small boxes if one must move (more comfortable to handle and also easier to put in a pocket).
Monocular or Binocular:
It is a question of the comfort of use. A binocular is more comfortable to use because it does not need to close an eye. But it’s usually more expensive.
If it is possible to find the best inexpensive night vision binoculars night vision binoculars, the best of the technology is out of the reach of the leisure user (several thousand euros). But we can see a suitable quality night vision device for less than 400 dollars.
