How far can I see how far can I see the principle of night vision telescope buying guide

1. What is the principle of night vision Telescope

1. principle

The microscopic night vision mirror (the same is true for the Telescope) to put the faint light, so under the circumstances that there is no light at all, the microcomio is not seen.

2. Principles of infrared night vision Telescope

This is the real military night vision mirror, There are two types of infrared night vision mirrors, one is active, the other is passive, and the active type is the night vision emitting a bunch of infrared rays. Essencequilt The dynamic type is to transform the infrared rays from the object itself into visible light. If there is no infrared source (most things that can generate calories can become infrared, such as creature, vehicles, flames, etc.), passive infrared night vision mirrors can not be seen. And active infrared night vision mirrors can be seen under any circumstances.

Second, night vision Telescope purchase

1. Active infrared night vision instrument applicable people: only at night.The main point of buying: The second generation is much better than the first generation. It is best to choose the second -generation night vision instrument.Try to choose the night vision instrument of your eyes, which is high, and it is much more comfortable to use than a single Tube.

2. Passive infrared thermal image instrument suitable for people: ultra -long night vision distance.The main purpose is to discover the goal, not to see the key points of the target details.

In summary, you must first know your needs. If you use it mainly at night, try to choose the night vision or thermal portrait.There are no two functions a volume, each with its own strengths.This can be practical.

Third, how far can night -view Telescope be seen

Many consumers do not understand this layer of concept. They believe that they can be seen one kilometer or two kilometers like ordinary Telescopes. In fact, these two products are not a concept. They are different.Observation.The principle is different, so when you look at the so -called parameters of the night vision instrument, don't believe in the indicators on the parameters. The most observation distance of the manufacturer's farthest observation generally has a large error and no reference value.Therefore, you cannot determine that the night vision is far away according to the parameters. The situation of the infrared auxiliary Lights is different. The distance of the situation of the infrared auxiliary light is different.In fact, this is very simple, but it is still difficult to explore than novices just exposed to this night vision instrument.Below I will talk about, under what circumstances can the night vision be seen?Under what circumstances is it close?

1 The night vision instrument observes a distance in the case of all black and light light

1) The distance from the micro -light observation is generally based on 1/4 The moon is based on the conditions of the weather. 50-400 Mi, if the weather is darker, or if the environment is harsh, its micro -light observation distance will be closer.At present, even the night vision instrument of more than tens of thousands of yuan can not be observed in the micro -light to reach 400 Above me.The second -generation night vision instrument can only be achieved 200 Du Mi, usually 1000-3000 The night vision around the yuan, its micr -light observation distance is 50 About meters.

2) In addition to the quality of the night vision instrument, the full black observation distance was seriously affected by the infrared lamp distance.At present, the infrared lamps equipped with the night vision instrument are average 50 About meters.Second generation The night vision can be observed under the observation of all black 100 About meters.In our actual use, there are very few all black conditions.For the second -generation night vision instrument, it is basically not all black when used outdoors.For a generation of night vision instruments, I said earlier, even darker, even if it was all dark.

2 The night vision instrument observes far and near the situation when the infrared is turned on and does not turn on the infrared.

At present, the night vision on the market, each model is different from the far exterior of the infrared and does not turn on the infrared.
