Expose the purchase points of infrared night vision devices for customers
Infrared night vision device purchase points To buy night vision devices, choose according to the following order: 1. Image enhancement tube: several generations. Be sure to confirm with the merchant when buying. Because the packaging and manuals of night vision devices generally do not indicate which generations of image-increasing tubes are used. Of course, if you want to buy a 2nd or 3rd generation night vision device, it is best to buy a thermal imaging camera that is clearly marked with several generations of image-increasing tubes, so as not to affect your rights and interests.
Infrared night vision device selection points
To buy night vision devices, choose according to the following order:
1. Image enhancer tube: several generations. Be sure to confirm with the merchant when buying. Because the packaging and manuals of night vision devices generally do not indicate which generations of image-increasing tubes are used. Of course, if you want to buy a 2nd or 3rd generation night vision device, it is best to buy a thermal imager that is clearly marked with several generations of image enhancer tubes, so as not to infringe on your rights and interests. At present, night vision devices such as FLIR in the market are marked on the product packaging and on the machine which generation of image intensifier tubes are used. the
2. Lens: Look at the lens caliber and magnification. Without considering the size, of course, the bigger the better. In the same case of the image intensifying tube, the principle is that the larger the aperture, the farther the observation distance is, and the clearer the image will be. the
3. Image enhancement technology: Generally, night vision devices with this technology will have better image brightness and clearer under the same conditions. the
4. Infrared emitter: The quality of this performance also directly affects the image quality. the
5. Resolution: The resolution of the lens is very important, the higher the resolution, the clearer the displayed image.
Classification of infrared night vision devices
1. According to the algebraic classification of image increasing tubes:
The most important index of infrared night vision device is the algebra of the image intensifying tube. Theoretically speaking, the higher the algebra, the farther and clearer the observation distance will be. the
2. Classification by observation eyepiece: it can be divided into monocular and binocular.
