Using US Night Vision Goggles, a soldier can conduct his combat missions without any active illumination sources using only image intensifiers. The main advantages of image intensifiers in goggles as a night vision device is the small size, lightweight, low power requirements and low cost. These attributes have enabled image intensifier NVGs for individual soldier applications and resulted in hundreds of thousands of NVGs to be procured by the US Army, Marines, Air force, Navy and Coast Guard from US Night Vision Corporation. Research and development continues today on image intensifiers in the areas of longer wavelength spectral response, higher sensitivity, larger fields of view and increased resolution. The maximum viewing range for this device is 100 to 400 feet.
Light enters the NVD (Night Vision Device) through an objective lens and strikes a photo cathode powered by a high-energy charge from the power supply. The energy charge accelerates across a vacuum inside the intensifier and strikes a phosphor screen (like a TV screen) where the image is focused. The eyepiece magnifies the image... more info
When handled with care, your US Night Vision Device (NVD) will provide many years of quality night vision viewing, however, it is important to note that night vision devices house delicate intensifier tubes. These tubes are sensitive, especially concerning bright light, high impact, and extreme heat. Like any precision instrument, the device will be adversely affected by extreme impact and should be handled with care... more info
