1、Blind pursuit of high indicators
Each product has a unique set of technical indications, and high indicators naturally indicate a product's relative performance. The viewing distance of night vision goggles is the most significant technical indicator. How far do night vision glasses have a range?
As for the response to this query, many retailers or brands may interpret it differently. For instance, a specific type of night vision gear sees a lot of sales. Some vendors even advertise that their night vision equipment can see up to 1000 meters away, but some consumers blindly buy into these so-called deals because they don't grasp the nature of the item and are only interested on high indicator values. Due to high-quality goods, purchasing mistakes are not unheard of.
The level of the image intensifier tube, the magnification, the size and transmittance of the objective lens, the infrared auxiliary light's irradiation distance, the size of the observation target, the usage of ambient light, and other parameters all affect the night vision device's seeing distance. The booster tube's level is one of the most crucial variables. The greater the viewing distance, the higher the level, higher the resolution, etc. The night vision equipment with higher infrared intensity and magnification will, of course, see farther if the same degree of image intensifier tube and resolution is utilized to examine the same target in the same environment.
The first generation night vision device has a viewing distance of approximately 20 to 50 meters when seven adults are viewed at a distance of one meter in 1/4 moonlight, while the second generation and second generation Plus night vision devices have viewing distances of approximately 60 to 80 meters. The third-generation and quasi-third-generation night vision systems have a viewing distance of 100–200 meters but a viewing distance of 500–800 meters. The information is incomplete and intended only as a guide.
2. About the price of night vision goggles
A generation-level night vision equipment costs hundreds to thousands of dollars, but the use effect and viewing distance are comparable, making it easy to meet the requirements for basic close-range target observation. You can select a cheap night vision equipment from a well-known manufacturer.
The second-generation night vision goggles cost roughly 10,000 yuan since foreign companies have monopolies on their own image-increasing tube technology and accessories, and more are imported. This sort of night vision equipment is utilized widely and has improved clarity and target identification due to its excellent performance. This kind of night vision device is a level that can accurately depict the performance of night vision devices, if price is not taken into account.
