What should I consider before buying an infrared night vision device?
1. Several generations of image-enhancement tubes. When purchasing, make sure to confirm with the seller. Because it is typically not stated on night vision equipment packaging or manuals which generations of image-increasing tubes are utilized. Of course, in order to protect your rights and interests, it is better to choose a night vision device that is clearly identified with many generations of image enhancer tubes if you want to purchase a second or third generation model. The generation of image intensifier tubes used in some products currently on the market, such the RHO night vision gadget from Russia, is identified on the product package and the machine.
2. Lens: Consider the magnification and lens caliber. Of course, the bigger the better, regardless of size. The idea holds true in the same situation as an image enhancing tube: the larger the aperture, the greater the observation distance, and the clearer the image.
3. Image enhancement technology: In general, under the same circumstances, night vision devices with this technology will have superior image brightness and clarity.
4. The performance of the infrared emitter has a direct impact on the image quality.
5. Resolution: The lens's resolution is crucial; the higher the resolution, the sharper the image that is exhibited.
The identification distance is the notional observation distance of the night vision gadget. There is no official standard, thus opinions range. There is actually no reference relevance. In general, the first generation can see objects clearly from a distance of 100 to 250 meters, the second generation from a distance of 200 to 350 meters, and the third generation from a distance of 300 to 500 meters. The resolution, infrared emitter, picture processing, and lens quality all play a role in this.
