Binocular infrared night vision is a common equipment for outdoor work at night, and it has been increasingly integrated into our lives and work. Infrared binocular night vision goggles are a common type of night vision goggles. When I buy a telescope, most people buy binoculars because binoculars are more suitable for our binocular observation. Therefore, when using binoculars to watch night vision goggles, it can also bring more convenience and comfort to work. In terms of performance, binocular infrared night vision goggles are obviously better than monocular infrared night vision goggles. In order to better watch at work and in life, binocular night vision goggles are the best choice. There are many binocular night vision goggles on the market. If you want to buy one, how should you choose it? What are the skills for choosing? Here I will introduce in detail the skills for buying binocular infrared night vision goggles. I believe it will be helpful to everyone.

1. Working principle of common binocular infrared night vision goggles

Nighttime binocular infrared night vision goggles with image intensifier as the core device, without infrared, use the reflected light of the target under weak light to enhance the visible image that can be felt by the human eye on the fluorescent screen through the image intensifier for observation. Ordinary people's eyes cannot sense infrared rays, so people cannot see anything without reflected light at night, and any object with a temperature higher than absolute zero is radiating infrared rays, including your body. Therefore, infrared rays are detected by a device that can sense infrared rays, and then this analog signal is processed by image processing methods such as background noise removal, amplification, and filtering to restore the outline of the detected object. However, it is difficult to restore the color, so the image seen by binocular night vision goggles is rarely in color. This is the working principle of common night vision goggles.

2. What are the common binocular infrared night vision goggles

Binocular infrared night vision goggles are divided into first-generation + night vision goggles and second-generation + night vision goggles. The price of first-generation + night vision goggles is about 3000-8000, and the price of second-generation + night vision goggles is about 50,000. The imaging of the first generation binocular night vision goggles is weaker than that of the second generation night vision goggles. There is also an absolute gap in performance. The second generation binocular night vision goggles can clearly see the target in very dim light conditions without turning on infrared. The observation distance of the second generation binocular night vision goggles can reach hundreds of meters. The second generation binocular night vision goggles are used by consumers with higher requirements for work, such as the military. I will briefly introduce several models of the first generation and second generation binocular night vision goggles with the largest sales on the market. For reference.
