Low-light night vision technology, also known as image intensification technology, is a photoelectric imaging technology that uses night vision goggles with image intensification tubes to enhance target images illuminated by weak light for observation. Low-light night vision equipment is currently the most produced and widely used night vision equipment in foreign countries.

Russian night vision devices mostly belong to the third generation of low-light night vision devices. They have improved the semiconductor material of the photocathode, making them sensitive to low light and infrared. They unify infrared night vision devices and low-light night vision devices into one instrument. , it functions as a low-light night vision device on sunny nights, and emits infrared rays as an active infrared night vision device on rainy and foggy nights, and its range is farther than that of the second generation.

Passed the test: The monocular night vision device generally can see about 10 meters without a transmitter when there is no light (no visible light, you can't see your fingers), and the transmitter can be used to see about 50 meters. The binocular night vision device is different from the distance model. You can see about 50-100 meters away. When there is visible light (low light such as: starlight, moonlight, street light, Puyun), you can see from hundreds of meters to several kilometers.
