Binoculars - Night Vision

Night Vision Binoculars amplify existing light, allowing you to see in dark conditions too dark for the naked eye. Night Vision scopes are comprised of high quality image intensifier tubes and optics. Night Vision monoculars and binoculars collect and amplify existing light through the objective lens, which is then focused on the image intensifier. Inside the intensifier, a photocathode is "excited" by the light and converts the photon energy into electrons. These electrons accelerate across an electrostatic field inside the intensifier and strike a phosphor screen (like a green monochrome TV screen) which emits an image that you can see. It is the acceleration of electrons, which provides gain and enhances the image. This is a Generation I Night Vision device.
