What are the product features and applications of infrared night vision devices?
The sight-type infrared night vision device is an electronic device that uses photoelectric conversion technology. Strictly speaking, the sight-type infrared night vision device is not a telescope, it is an electronic device that uses batteries. There are two types: active and passive. The active one emits a beam of infrared rays, which shines on the object and then reflects back, which is equivalent to a flashlight; the passive one amplifies the infrared rays emitted by the object itself and converts it into visible light.
It is a compact and beautiful handheld night vision device for monocular observation. Its optical system and bright imaging high-performance generation plus low-light tube will give you a clear and sharp observation effect. The sight-type infrared night vision device uses advanced integrated production technology, is compact in size, and weighs only 405g, making it easy to use for a long time.
Standard accessories include: power adapter, USB cable, video cable, lens cover, wrist strap, lining bag, quick start guide foldout, shoulder strap
Optional 40mm lens (field of view 9.3°×7.0°)
The sight-type infrared night vision device has a built-in long-range infrared laser illuminator to ensure that you can observe clearly even in a completely dark environment. The sight-type infrared night vision device uses an advanced new generation of image sharpening technology to generate a clear field of view, a longer observation distance, and richer observation details.
What is particularly noteworthy is that the sight-type infrared night vision device has a safe anti-glare function to ensure that the equipment is not subject to accidental and irreparable damage. This is greatly different from night vision equipment that is usually easily damaged when exposed to strong light, allowing you to use it with peace of mind and comfort.
The instrument has an extremely wide range of applications and is suitable for night patrols and reconnaissance of security guards. Whether you are traveling, camping, observing in the wild, or protecting your property from being stolen, the sight-type infrared night vision device can effectively provide you with help and cooperation. It is an ideal device for both military and civilian use, which not only enhances your work efficiency but also adds fun to your life.
There are many types, but they basically consist of optical systems, variable image tubes or micro-light tubes, power supplies and power supply systems. Of course, active infrared night vision devices must also be equipped with infrared searchlights, in which the variable image tube or low-light tube is the "heart" of the night vision device. The variable image tube can convert the invisible infrared image into a visible image, while the low-light tube can enhance the weak light tens of thousands or even hundreds of thousands times, making it detectable by the human eye.
Observation-type infrared night vision devices are afraid of strong light because the variable image tube and low-light tube are afraid of strong light. Taking the variable image tube as an example, when infrared light shines on the photocathode of the variable image tube, the photocathode emits electrons. Under the action of the high-voltage field (16 to 21 kV) and the electron lens, the electrons accelerate toward the fluorescent screen, causing the fluorescent screen to Displays a visible target image. The more light signals the variable tube receives, the more electrons are emitted. The light signals emitted by the fluorescent screen are stronger, and the images seen are brighter.
They are basically proportional. However, if the external light is too strong, the number of electrons emitted by the photocathode will stop increasing to a certain extent, that is, it will be saturated, and the target will not be visible clearly. If too strong light suddenly strikes, it may burn out the photocathode of the tube and prevent it from emitting electrons. Of course, nothing can be seen.
Although the sight-type infrared night vision device takes certain measures to prevent strong light, its effect is limited, so it must be operated strictly according to the regulations when using it. When encountering strong light or calibrating the target during the day, put on the objective lens cover or turn off the power switch. Proper use of sight-type infrared night vision devices can extend the service life of the sight-type infrared night vision device and avoid unnecessary damage, thereby giving full play to the role of the sight-type infrared night vision device.
