Bushnell Night Vision products are comprised of high quality image intensifier tubes and optics. Bushnell Night Vision products amplify existing light, allowing you to see in dark conditions too dark for the naked eye. HOW NIGHT VISION WORKS Bushnell Night Vision products 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. Your Night Vision device is ideal for a variety of professional and recreational uses including the following: Wild Life Observation, Astronomy, Boating / Marine Use, Police / Law Enforcement, Search and Rescue, Security, Property Management GETTING STARTED Installing Batteries This device operates on two AA batteries. To install, unscrew the battery compartment cover located on the bottom of the unit.
