How to buy a good enough night vision device?

Now, we start to share with you some dry facts to help people who wish to buy a night vision device to buy one that meets their requirements.

Classification of night vision devices:

First of all, Night Vision Devices (Night Vision Devices) are categorized into Infrared Night Vision (Infrared Night Vision), Laser Night Vision (Digital Night Vision) and Shimmer Night Vision (Image Intensifier). After testing these three types we can tell you with confidence that the Microlight Night Vision is the only night vision device worth buying. The principle of Image Intensifier is to use an image intensifier tube to amplify the brightness of an existing light source by thousands or even tens of thousands of times. It is also by far the most common type of military night vision device.

Depending on their military use, night vision devices are also categorized into Night Vision Goggles, which are attached to a helmet or hat to allow the user to see continuously at night, and Night Vision Scopes, which are attached to a helmet or hat to allow the user to see continuously at night. The Night Vision Scope, on the other hand, is mounted on a rail and is used for quick aiming and shooting. Typically, the Night Vision Scope has magnification, while the Night Vision Goggles have no magnification. 

Night Vision Scope

Based on the number of eyepieces in a night vision scope, night vision scopes are categorized as Monocular (monocular night vision scope) and Binocular (binocular night vision scope). The advantage of monoculars is that the user can adapt quickly, but the disadvantage is that it is difficult to judge the distance and depth of an object with one eye. Binocular night vision makes it easier for the user to judge the distance and depth of an object, so it's great for driving vehicles and helicopters, or for medical rescue, but the disadvantage is that it takes a long time for the user to get used to it.
