Top things you should consider before buying night vision goggles


Top things you should consider before buying night vision goggles

So, you decided to buy night vision goggles.

The most important feature of goggles (unlike binoculars, monoculars, and most telescopic sights) is that the goggles have no magnification. This is necessary for moving - on foot or driving a vehicle (car, ATV). After all, only with night vision goggles, one can estimate the distance to the visible object.

The second use of goggles is the use of shooting on a weapon with a nightvision compatible sight or laser (infrared IR) for hunting.

Our today's selection of TOP Night Vision Goggles is compiled:

·         AGM WOLF-7 NW2

·         Pulsar Challenger GS 1x20

·         Yukon Tracker 1×24

But first of all, it is important to take into account the fact that there are several points to pay special attention to before rushing to the store and buying night vision goggles. Before going straight to the Night Vision Store, you may have to consider a few difficult points, starting with what weather conditions will be in the area where you intend to use the goggles, and ending with why you buy Night Vision Goggles.

Top Factors to Consider When Buying Night Vision Goggles

Night vision goggles are perfect for all situations where you need to spend a long time watching. Compare the goggles with other devices that use a tube with an improved image. Night vision binoculars and monoculars have one major drawback: they occupy your hands. However, such a device can be quite heavy and holding it in your hands all the time can be tiring.

So, the first and most important advantage to goggles is freeing up your hands.

What else should you pay attention to when buying night vision goggles?

·         The image intensifier tube generation or light amplification principle (digital, thermal image, IIT) is used. This influences not just the image quality and observation range, but also the cost of the goggles;

·         Manufacturer. When choosing the manufacturer of the device, pay attention to the presence of a service center that services your location/area;

·         Price. Correspond the cost of the device to the benefit it will bring. Consider the tasks that you intend to accomplish with your night vision goggles. Do not buy models that are too expensive for fun or cheap for serious work.

Now let's take a closer look at the important parameters of the device. Then your purchase of goggles will bring you maximum benefit.

Generations

Image intensifier tubes today are divided into three generations. The highest quality, contrast and sharpest image is provided by the image intensifier tube of the third generation. They differ in their advantageous direction both in weight characteristics and compactness. But the cost of a device made using this technology will be very significant.

Conclusion: the more modern the converter design, the better the image quality and high optical performance can be expected from the goggles themselves.

Night vision specifications

This optical device is based on an electronic converter (imagefier tube), which can amplify weak light many times. Thus, night vision goggles, as any other device based on image intensifier tubes (night monoculars, binoculars, passive night sights, etc.) do not allow you to see in absolute darkness. But if there is at least some light on the terrain - the image intensifier tube will amplify it many times and will allow the person wearing night vision glasses to see well what is happening around.

On this basis, you should definitely think about the industry in which you are going to use night vision goggles. The list is very wide, but we will try to tell you briefly. Where the Night Vision Goggles are used:

·         night vision goggles;

·         night photography and video shooting;

·         for military and special operations;

·         patrolling;

·         object security;

·         air and sea navigation;

·         hunting and animal watching.

Each of the branches has its own specification. But do not forget that glasses have technical properties that you should pay attention to. Let us now consider each of the parameters in more detail:

Resolution

This parameter characterizes the ability of the device to display two close points or lines separately. Typically, the resolution is given in dashes per millimeter (lpm). The higher the resolution in the dashes per millimeter (lines) and the lower the angular value, the higher the resolution. The higher the resolution of the device, the clearer the image can be seen by the observer.

Magnification and Field Of View

Unlike binoculars, night vision goggles are not capable of magnifying an image. However, this is not always a disadvantage. Magnification of 1x provides the widest possible field of view, which in many cases is much more important.

Spectrum

The device increases the brightness of the object thousands of times. This can be natural light or IR illumination, which is converted into visible spectrum. The UV range extends from 100 to 400 nm, while the near ultraviolet range nominally extends to the lower limit from 300 to 400 nm, while the visible part of the spectrum can expand significantly and extend from 400 to 750 nm.

Weather Resistance

Make sure that the lightweight body of the glasses you buy is made of superstructural plastic. Also, that the case is waterproof and able to withstand heavy shock loads.

Batteries

Night vision goggles need their own source of electrical energy, which plays the role of chemical batteries - batteries, most often lithium. The longer the battery life, the less frequently you will have to change the batteries and the less likely it is that your goggles will suddenly fail due to a failing power source.

Weight, User-friendliness, And Size

Night vision goggles are easy to use because of their light weight and size. The device will have to be worn on your head all the time. From the excessive weight of the device users may feel uncomfortable. Therefore, pay special attention to the weight of your device. Also, make sure that the helmet or skull crusher with the mobile monocular attachment fits the size of each head or helmet.

 Instead of confinement: Night Vision Goggles are the most convenient night vision device for long-term observation and situations where it is important to free your hands. Night vision goggles are suitable for hunters, military, police, rescuers, night nature researchers, speed bumpers, tourists and climbers.
