 Night-vision goggles host, wearing a vehicle, incorporating packet, the original specification 

 Bushnell Night Vision product through the eyepiece to focus light onto the image intensifier capture and enhance existing light, the enhanced inside, a photo-cathode will be light "activation", and the photon energy into electrons in the electron through a enhancer is accelerated inside the static region, the impact of P on the screen surface (as if a green TV screen), to form an image visible to human eyes. After the electron acceleration, increased brightness and image clarity.

 Night Vision tips 
 * Night vision do not usually make sure the front cover when the cover must not be under the day or bright start! Can never look directly at a centralized source, such as headlamps, flashlights, Fluorescence, and the moon and so on! Otherwise it will cause circuit overload and burn! 

 * The basic principles of night vision goggles, the environment is "a bad light," amplified by photoelectric conversion, a visible image. 
 If no light in total darkness is ineffective, old friends called "Stars" night-vision goggles, which means it needs to function under dim light. 
 Therefore, regular built-in night vision goggles now invisible infrared light to fill light, so that the black within a certain distance of your target environment is still visible. After use, immediately cover the front cover and remove the battery to close at special package to prevent inadvertent inadvertently open! Key for night-vision goggles to see in a very dark under the target, it takes a large caliber, low magnification wide field of view and, generally 5 times. Night Vision Goggles are all monochrome images (green or black and white), no color night vision goggles. Not only because of night vision optical lenses, the internal sensor and electronic circuits as well, so they did not turn on the power of the situation, the viewfinder is dark can not see anything off, the viewfinder may be the remnants of the green will gradually take a few minutes away completely dark, this is normal. Small hole in the front cover only test you during the day, please remember only
