Buying Guide and Facts for night vision binoculars
Night vision binoculars works by gathering the existing light forms such as light from the moon and or stars or alternatively through the infra-red light situated at the front of the lens. The source of light is made up by the photons that go into the photocathode tube and then change into electrons. These electrons then become amplified as they go through the electrical and chemical process. The electrons are then thrown at the phosphorus screen where they are changed into amplified electrons morphing into visible light which the viewer can then see through their viewing piece. The image portrayed are then a clear amplified recreation of what the user was trying to observe.
Night Vision Devices can be either 1st, 2nd, or 3rd generation, and this stands for the type of light intensifier tube that the device has and it is this light intensifier tube that is probably the most important property of a night vision device.
