Product features and application of infrared night vision device
The sight and sight infrared night vision device is an electronic device that uses photoelectric conversion technology. Strictly speaking, the sight-and-see infrared night vision device is not a telescope, it is an electronic device that uses batteries. There are two types of active and passive. The active one can emit a beam of infrared rays, which can be reflected on the object and then reflected back, which is equivalent to a flashlight; the passive one is to amplify the infrared rays emitted by the object itself and convert it into visible light.
This instrument is a compact and beautiful hand-held night vision device for monocular observation. Its optical system and bright imaging high-performance first-generation microlight tube will bring you a clear and sharp observation effect. The sight and sight infrared night vision device adopts advanced integrated production technology. It is small in size and weighs only 405g, and it is handy for long-term use.

The built-in long-distance infrared laser illuminator of the aiming infrared night vision device ensures that you can also observe clearly in a completely dark environment. The aiming-type infrared night vision device uses advanced new-generation image sharpening enhancement technology to generate a clear field of vision, a longer observation distance, and more detailed observations.
It is particularly noteworthy that the sight-and-see infrared night vision device has a safe anti-glare function to ensure that the device is not subject to accidental and irreparable damage. This is greatly different from the night vision equipment that is usually easily damaged when encountering strong light, so that you can use it with peace of mind and comfort.
The instrument has a wide range of applications and is suitable for night patrol and reconnaissance of security guards. Whether you are traveling, camping, observing in the field, or protecting your property from being stolen, the aiming infrared night vision device can effectively help and cooperate with you. It is an ideal equipment for both military and civilian use, which not only enhances your work efficiency but also adds to your joy of life.
There are many types, but basically they are composed of optical system, image changing tube or micro-light tube, power supply and power supply system. Of course, the active infrared night vision device must also be equipped with infrared searchlights, among which the image-changing tube or low-light tube is the "heart" of the night vision device. The image-changing tube can convert the invisible infrared image into a visible image, and the micro-light tube can enhance the weak light by tens of thousands or even hundreds of thousands of times, so that the human eye can perceive it.
The point-and-shoot infrared night vision device is afraid of strong light, because the image converter and micro-light tube are afraid of strong light. Taking the image transformation tube as an example, when the infrared light is irradiated on the photocathode of the image transformation tube, the photocathode emits electrons, and the electrons are accelerated to the fluorescent screen under the action of a high-voltage field (16-21 kV) and an electronic lens, so that the fluorescent screen Displays the visible target image. The more light signals received by the imaging tube, the more electrons are emitted, the stronger the light signals sent by the fluorescent screen, and the brighter the image seen.
They are basically proportional. However, if the external light is too strong, the number of electrons emitted by the photocathode will not increase to a certain extent, that is, saturation will occur, and the target will not be seen clearly. If too strong light suddenly shoots over, it may also burn out the photocathode of the tube, so that electrons cannot be emitted, and of course nothing can be seen.
Although the aiming infrared night vision device has adopted certain anti-glare measures, its effect is limited, so it must be operated in strict accordance with the regulations. When encountering strong light or targeting during the day, put on the objective lens cover or turn off the power switch. Proper use of the aiming infrared night vision device can prolong its service life and avoid unnecessary damage, so as to give full play to the role of the aiming infrared night vision device.
