Key Points for Selecting and Purchasing Infrared Night Vision Devices
Key points for purchasing infrared night vision devices: 1. Choose a night vision device in the following order: Augmentation tube: It is of several generations. Be sure to confirm with the merchant when making a purchase. Because the packaging and instructions of night vision devices generally do not indicate the generation of the amplifier tube. Of course, if you want to buy a 2nd or 3rd generation night vision device, * it is good to buy an infrared thermal imager with a clear label indicating which generation it is, in order to avoid your rights being affected
Key points for purchasing infrared night vision devices
Purchase night vision goggles and select them in the following order:
1. Image intensifier tube: It is of several generations. Be sure to confirm with the merchant when making a purchase. Because the packaging and instructions of night vision devices generally do not indicate the generation of the amplifier tube. Of course, if you want to buy a 2nd or 3rd generation night vision device, it is recommended to purchase a thermal imager with a clear label indicating which generation of image intensifier tube it is, to avoid any infringement of your rights. At present, night vision devices such as FLIR on the market indicate on product packaging and machines which generation of image intensifier tube they are using.
2. Lens: Check the aperture and magnification of the lens. Without considering volume, of course, the larger the better. In the same case of an image intensifier tube, the principle is that the larger the aperture, the farther the observation distance, and the clearer the image.
3. Image enhancement technology: Night vision devices equipped with this technology generally have better and clearer image brightness under the same conditions.
4. Infrared emitter: The performance of this emitter directly affects the imaging quality.
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. Classified by the generation of the image intensifier tube:
The main indicator of infrared night vision devices is the generation of the image intensifier tube. In theory, the higher the generation, the farther and clearer the observation distance.
2. Classified by observation eyepiece: can be divided into single tube and double tube.
