How to choose a night vision device: prices, description, reviews

A night vision device can be either an optical or a digital device. There are quite a few varieties of the device, depending on the purpose, they serve for observation or accurate shooting in the dark.

General information

Before choosing a night vision device, you should pay attention to such indicators as size, range and angle of view, as well as the ability to focus on a specific goal. Such devices can be not only built-in, but also removable, serving for additional lighting at night. Depending on the amount of incoming light in the lens, choose its diameter. Its maximum value is 60 mm. Another important characteristic is the viewing angle, where the largest value is x1. The clarity of the observed image depends on the generation of the device. The newer it is, the higher the light gain.

Night Vision Devices: description, principle of operation

To date, this equipment is quite popular. Many people are wondering how to choose a night vision device. First you need to determine the type of this device.

1. Monoculars. This device is the most popular not only for amateurs, but also for professionals. Outwardly it looks like a telescope, which has an objective. Thanks to the eyepiece, you can observe various objects at a great distance. The simplest and cheapest are monoculars of the first class. They are able to see the object at a distance of 300 meters. The next class is of a professional type with a detection range of 600 meters. Monoculars of the latest generation are equipped with a special long-range eyepiece, and also have a large viewing angle.
2. Night vision goggles. This device is a binocular built into a special mask. She puts on her head. The main advantage is that the hands remain completely free. Therefore glasses are used by drivers, rescuers, climbers, etc. As a rule, an adjustable illuminator is built in the glasses, due to which the viewing range is 600 m. Their main feature is the absence of multiplicity. Thus, at a certain distance, you can consider the clear outlines of objects.
3. Binoculars. They are no less popular than the previous species, and also available in two versions. Such a universal apparatus is capable of solving a variety of tasks to observe in the dark. This is an excellent night vision device for hunting. Used for performing search operations, as well as for monitoring a certain territory. In comparison with previous species, binoculars have a huge multiplicity, so the range is much higher. Their technical characteristics depend on the generation. Also there are binoculars with a built-in video camera capable of recording all the movements that occur.
4. Sights. This is a special class of night vision devices, which is used not only for observation, but also for accurate shooting. They are installed on different types of weapons. If a person has sufficient experience, then the shots will be accurate. Like all models, the sights are divided by generations. Representatives of the first generation are able to recognize the target at a distance of more than 150 m. If you look at the sights more modern, they are able to see clear contours at a distance of 900 m and above. They are available in two types. The digital night vision device differs from the optical device by its design.

Design

Before choosing a night vision device, you need to understand its design. It does not affect the distance of the inspection in any way, but makes the process more comfortable. If you change the structural elements of the instruments, then the objects may have a small clarity. In the lens will be visible only a part of the image tube, and its replacement is quite expensive. For sights, an important point is the presence of a sufficient distance from the instrument to the eye so that when shooting, do not get injured. Most domestic manufacturers perform high-quality devices with glass optics, but such a device has a high price. There are also cheap devices with plastic elements, but the quality will be much worse.

What is an infrared illuminator?

This device serves to illuminate a specific area or object, so it's more convenient to watch it. They must be installed when there is insufficient natural light. They can consist of a laser, LEDs or other lamps. The laser has a negative effect on the person's vision. Therefore laser lighters are often forbidden. The LEDs and lamps, as a rule, with a capacity of 12 mW are safer. The domestic market produces the most powerful illuminator - 75mW. Thanks to him, the range of inspection increased several times. If this device is not built into the night vision device, it can be purchased separately. In general, the reviews of those who use such an infrared illuminator are only positive.

Main characteristics

Among the instruments of night vision there is the following pattern. The smaller the dimensions, the greater the viewing distance. Particular attention should be given to the sights. First of all, their design must withstand the loads that arise during shooting. In this case, the sight should not be strayed from its original position. In addition, the target should be clearly visible under all operating conditions. Most of the sights delivered to the market do not meet the requirements for impact characteristics. They can be installed on certain weapons when obtaining a license.

Tips for buying

To properly select a night vision device, you must adhere to the following rules:

• If the device is not used in professional activity, then it is not necessary to select a device with improved technical characteristics, since the value depends on this;
• To make the image quality, you should choose a device with an opening of at least 1.5;
• When buying a device, you should pay attention to the manufacturers, carry out the transaction where the warranty card is issued;
• Before buying it is better to test the device to see if it suits you or not;
• Before buying it is necessary to check its working capacity.

Night vision device: price

The cost depends on the technical characteristics, as well as on the type of device. So, the price policy of these devices is within the following limits:

• Monoculars from 1000 to 40 000 rubles;
• Night vision goggles from 1000 to 180 thousand rubles;
• Binoculars from 20 000 to 50 000 rubles;
• Sights from 30 000 to 600 thousand rubles.

Conclusion

Many people who use night vision devices leave good reviews. Each type is designed to improve the quality of surveillance in the dark. Before buying, you need to know clearly for what purposes the device will be used. If for amateur observation, then a night vision device, whose price is lower, will do. For professional activities, it is worth purchasing devices with improved technical characteristics.
