What is a low light night vision device
Principle: The instrument uses natural light such as night sky light, star moonlight, atmospheric glow and other natural light reflected by night targets to enhance and magnify it to hundreds of thousands of times, so that it is suitable for reconnaissance, observation, aiming, vehicle driving and other battlefield operations at night with the naked eye. .
Features: Because the low-light night vision device uses night sky light to work, it is a passive way of working, so it can hide itself better, and it is suitable for departments engaged in special work, such as military, criminal investigation, drug collection, private collection, night monitoring, and security. It is the most suitable for applications, etc.
The low-light night vision device has been developed for three generations, and the first generation is a three-stage cascaded low-light night vision device (composed of three 0-generation photocells connected in series). The second generation is a micro-channel plate low-light night vision device, and the third generation is a |||-V group negative electron affinity photocathode image intensifier low-light night vision device. When the first generation transitioned to the third generation, a super-second-generation photocell was developed, called the second-generation plus, whose technical performance was second only to the third-generation products. If the low-light night vision device is subdivided, it is 0 generation, 1 generation, 2 generation, 2 generation plus, 3 generation, a total of five grades. Low-light night vision devices have been developed to this day. They are relatively mature in technology and have good imaging quality and low cost. Therefore, they will still be a major part of the world's night vision equipment for a considerable period of time in the future. The second-generation plus and third-generation products have the characteristics of small size, light weight, clear image, complete functions, and practicality. It is an indispensable equipment for night work in military, public security, armed police, customs, oil industry, news gathering, tourism, aquaculture, nature lovers, and other industries. However, because the low-light image intensifier, its core component, is a high-tech product, the process is particularly complicated, the cost is high, and the price is relatively high. But in terms of cost performance, it is quite good.
