1. Intensifier tube: It is several generations. Be sure to check with the seller when buying. Because the night vision device packaging and instructions are generally not marked with several generations of imaging tubes. Of course, if you want to buy a 2nd or 3rd generation night vision device, it is best to buy a night vision device that is clearly marked as several generations of image-enhancing tubes, so as not to infringe your rights. At present, the night vision devices such as Russia's RHO are marked on the product packaging and machines as the use of the first generation of imaging tubes.
2. Lens: Look at the lens diameter and magnification. Without considering the volume, of course, the bigger the better. In the case of the same intensifier tube, in principle, the larger the aperture, the farther the observation distance, and the clearer the image.
3. Image enhancement technology: Generally, night vision devices with this technology will have better image brightness and clearer under the same conditions.
4. Infrared transmitter: The quality of this performance also directly affects the image quality.
5. Resolution: The resolution of the lens is very important, the higher the resolution, the clearer the displayed image.
Infrared night vision device classification
1. According to the algebra of the intensifier tube:
The most important indicator of the infrared night vision device is the algebra of the imaging tube. In theory, the higher the algebra, the farther and clearer the viewing distance will be.
2. According to the observation eyepiece classification: it can be divided into monocular and binocular.
