Difference Between Night Vision Generations

Each stage of human history is characterized by a certain development, new ideas, and their implementation. Starting from the most ancient times, man has always sought to improve, improving the standard of living in every possible way. Primitive people, not having any ideas about the world and its functioning, made attempts to make such devices or primitive mechanisms that would facilitate the implementation of everyday household tasks. The creation of a spear, hammer, bow and arrow, scraper, hacksaw, and other similar things relates to this desire. With each century, mankind improved more and more and sought ways to solve problems that were relevant throughout the entire time of the continuous existence of mankind. This is how the Internet was invented, which made it possible to connect various people from all corners of the world in communication and in the search space. The invention of the wheel at different times made it possible to create means of movement of people between villages and cities. The telephone has become another means of communication between people and an opportunity to solve all matters that need to be done at a certain time without leaving home. You can have long discussions about such inventions and each time conclude about their usefulness and relevance.

A separate group of inventions is those that require long research and the use of the highest quality materials for their manufacture due to their special purpose and importance for different groups of society. It is primarily about devices that are used in military affairs and for the performance of strategically important tasks for the country. One of these devices is a night vision device. These are binoculars, monoculars, devices with thermal imaging properties, etc. Their main purpose is, first, to obtain an image of objects that are in a poorly lit area. These devices are legalized in most countries of the world and are actively used in various spheres of life. However, before they became as effective as they are today, their improvement went through four generations, each of which had its own characteristics and traits that distinguished them from one another. It is the generation of night vision devices that will be discussed further.

Night Vision Gen 1

Night vision devices of the first generation are primarily characterized by their ease of use and rather primitive technologies compared to subsequent generations. Such devices are relatively cheaper and more accessible for purchase. In addition, the area of ​​illumination and fixation of the image is quite small and does not allow us to see something at great distances. Also, the devices of the first generation do not give a clear picture when they are used, because they are not yet equipped with the latest technologies responsible for image quality. They are not able to convey the movements of objects at their natural speed and display reality mostly in gray without distinguishing objects at all. The disadvantage of first-generation devices is also their short operating time. Yes, the autonomous operation of these devices is no more than 2-3 hours of active use. Since the first-generation night vision devices emit a lot of light, they distort the image somewhat and are not practical to use, for example, by hunters who want to remain invisible to animals or other people. The first generation also does not function for long. It goes through approximately 500-1000 charging cycles and begins to lose its original functions for which it was purchased. However, for ordinary simple purposes in various fields of activity, they will still come in handy since they cover basic needs 100 percent and are available for purchase by almost every able-bodied person.

Night Vision Gen 2

The second generation of night vision devices was marked by significant progress compared to the first generations and is more productive and technological. The first thing that catches your eye is the higher quality of the image and the absence of defects in the reflection of reality through the lens. Also, the continuity of operation of devices of the second generation is much longer than that of devices of the first generation. The newer generation also demonstrates more efficient autonomous functioning compared to its predecessors. These devices have a much wider scope of use and recognize objects even in the smallest light. In the end, the second-generation devices have a wider area for displaying the situation and are more similar in their efficiency to the third-generation devices, which will be discussed further.

Night Vision Gen 3

The third generation of night vision devices is the benchmark for almost all regular users of such devices. It is the devices of this generation that are actively used in military affairs for reconnaissance, surveillance of the area and the performance of important combat tasks. This already gives an idea of ​​the extraordinary performance of these devices and the much higher quality of their work, compared to previous generations. A noticeable improvement is the increased peak performance of third-generation devices and their ability to operate autonomously three times more efficiently than their predecessors. Also, these devices work at any level of illumination, even at the weakest. This allows special services to perform secret tasks and remain unnoticed. The quality of the image on these devices is impressive because the image is transmitted almost the same as in the original. That is, the devices of the third generation are state-of-the-art and create opportunities for their users to fully enjoy their performance and the results of their work.

Night Vision Gen 4

It should be noted that no one officially singles out the fourth generation of night vision devices. You can find information about them on some sites, where the main goal is to attract the attention of the buyer to the newest devices that can be purchased at a high price. At the same time, there were some attempts to single out devices of the fourth generation, but they did not pass the test of compliance with the requirements set before them during research. That is why, in fact, the devices of the fourth generation are the same devices of the third generation, but with some not very noticeable improvements. In specialized stores, such devices will be classified as third-generation, because this is officially correct.

White Phosphor Technology (WPT)

White phosphorus technology is available for all generations of night vision devices. Its main purpose is to demonstrate the highest image quality and the most accurate reflection of reality. In addition, this technology allows you to get high-quality black-and-white images, instead of black or green images, as it was before. White phosphorus technology in night vision devices is actively used by the military, as well as law enforcement and search and intelligence agencies. It provides wide opportunities to its users and deserves the attention of specialized institutions, for which the main tasks are the preservation of people’s lives or the protection of strategic objects.

So, night vision devices have undergone a significant evolution from the simplest devices to technological and maximally productive devices that are used in various spheres of life and contribute to the effective performance of the tasks set before them. Buying one or another night vision device, even of the first generation, is already better than doing some activity in the night light on your own because even the very first such devices gave results when they were used. The main thing is to understand the goals pursued by the user and to use these devices for their purpose.
