The night vision device converts the invisible light (low light or infrared light) signal from the target into an electrical signal, and then amplifies the electrical signal, and converts the electrical signal into an optical signal visible to the human eye. Night vision products use the objective lens to focus the light on the image intensifier to collect and enhance the existing light. Inside the intensifier, a photocathode is "activated" by light and converts photon energy into electrons. These electrons pass through an image intensifier. The electrostatic area located inside the intensifier is accelerated and hits the phosphor surface screen to form an image visible to the human eye.
