What about infrared night vision product features and applications?
Viewing type infrared night vision device built-in long-distance infrared laser illuminator, to ensure that you can also be clearly observed in total darkness. Viewing type infrared night vision device utilizes advanced new generation of image sharpness enhancement technology to generate a clear field of view, a longer observation distance, observation details are more rich.
Particularly noteworthy is that the viewer 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 the usual night vision equipment that is easily damaged by bright 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 by security guards. Whether you are traveling, camping, field observation, or to protect their property from theft, viewing type infrared night vision device can effectively provide you with help and cooperation. It is the ideal equipment for military and civilian dual-use, which enhances your work efficiency and adds fun to your life.
There are many types, but basically consists of optical system, variable image tube or micro phototube, power supply and power supply system and so on. Of course, the active infrared night vision device should also be equipped with infrared searchlight, which varistor or microlight tube is the "heart" of the night vision device. Variable image tube can be invisible infrared image into a visible image, microlight tube can be a weak light to enhance tens of thousands of times or even hundreds of thousands of times, so that the human eye can be perceived.
Observation type infrared night vision device is afraid of bright light, because the varactor tube and the microlight tube is afraid of bright light. Variable image tube, for example, when the infrared light irradiated to the variable image tube photocathode, photocathode emission of electrons, electrons in the high-pressure field (16 ~ 21 kV) and the role of electronic lenses, accelerated to the fluorescent screen, so that the fluorescent screen displays a visible image of the target. Transducer receives more light signals, the emission of electrons is more, the fluorescent screen emits a strong light signal, see the image is also bright.
They are basically proportional. However, if the external light is too strong, the photocathode emits more electrons to a certain extent does not increase, that is, saturation occurs, it will not see the target. If too strong light suddenly shot over, may also make the tube photoelectric cathode burned out, and can not emit electrons, of course, nothing can be seen.
Although the viewing type infrared night vision device to take certain measures to prevent glare, but its role is limited, so the use of must be strictly in accordance with the provisions of the operation. When encountering bright light or daytime target calibration, the objective lens cover should be put on or turn off the power switch. Correct use of the observation type infrared night vision device, you can extend the observation type infrared night vision device its service life and avoid unnecessary damage, so as to give full play to the role of the observation type infrared night vision device.
