HOW NIGHT VISION WORKS
Bushnell Night Vision products amplify existing light, allowing you to
see in dark conditions too dark for the naked eye.
Bushnell Night Vision scopes are comprised
of high quality image intensifier tubes and optics.
Bushnell 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.
