Infrared Night Vision Selection Points
Buying a night vision device, the choice is made in the following order:
1. Booster tube: It is several generations. When you buy, be sure to give merchants to confirm. Because the night vision device packaging and instructions are generally not marked on how many generations of booster tubes. Of course, if you want to buy 2 or 3 generations of night vision devices, it is best to buy a clearly marked is a few generations of booster tube night vision devices, so as to avoid infringement of your rights and interests. Currently on the market, such as the Russian RHO night vision device in the product packaging and machines are marked on the use of the first generation of the tube.
2. Lens: look at the lens calibre and magnification. In the case of not considering the volume, of course, the bigger the better. The same tube situation, in principle, the larger the calibre, the greater the observation distance, the clearer the image.
3. Image enhancement technology: generally with this technology night vision device, under the same conditions the image brightness will be better and clearer.
4. Infrared emitter: this performance is good or bad, but also directly affects the image quality.
5. Resolution: the resolution of the lens is very important, the higher the resolution, the clearer the image displayed.
Infrared night vision classification
1. According to the classification of the incremental tube generation:
The most important indicator of infrared night vision is the number of generations of intensifier tubes, theoretically speaking, the higher the number of generations, the longer the observation distance, the clearer.
2. according to the observation eyepiece classification: can be divided into monocular, binocular.
