What are the differences between different generations of night vision products?
The main difference is the advancement of booster technology. The first generation uses an intensifier tube to enhance the brightness of the surrounding environment, which can accelerate the flow of electrons to hit the phosphor surface, just like the principle of a TV screen. Generation II devices, on the other hand, added a micro-frequency disk, which increased the number of electrons striking the phosphorous surface, thereby enhancing brightness. Gen III devices add a gallium arsenide photocathode, which produces a higher number of photoelectrons than Gen II.
Theoretically, both the second generation and the third generation have made great progress in improving brightness, but their prices are relatively expensive, which discourages most customers. Its price is generally above 20,000 yuan. This year, with the advancement of technology, many excellent 1st generation + night vision devices have emerged. By reminding the quality of the 1st generation + image enhancement tube and adding image enhancement technology, the actual effect of some 1st generation + night vision devices It has reached and approached the second generation of night vision products. One of the most representative is a binocular binocular night vision device - Alpha ORPHA TRACKER tracker 560.
This device uses the latest image enhancement technology, and because it is binocular and dual-purpose, the light transmission rate of the night vision device is doubled, and it also has its unique internal optical lossless technology. The actual use effect of this binocular night vision device has reached the level of the second generation, and its price is only about $800, which is much lower than the $2,000 price of the ordinary second-generation monocular night vision device. At the same time, it has binoculars, which is more convenient to use than single barrels. Therefore, since this night vision device was launched in Germany in 2010, it has directly impacted the market of the second-generation night vision device, and at the same time, many customers who were dissatisfied with the first-generation night vision device turned to buy this night vision device. In 2011, the market survey conducted by the American Optical Window Weekly showed that this binocular night vision device ranked first in the sales volume of the United States in 2011, and its sales volume exceeded that of the low-priced monocular night vision device, becoming a new generation of night vision device. champion.
