How do night vision binoculars work?

Night vision binoculars are fascinating devices that allow us to see in low-light conditions and even in total darkness. They utilize advanced technology that involves several key components to function.
Firstly, night vision binoculars have objective lenses that gather available ambient light, such as moonlight or starlight, and pass it through an image intensifier tube. This tube amplifies the incoming light using a photocathode, converting photons into electrons.

The intensified electrons then pass through a microchannel plate, where they undergo rapid multiplication, significantly increasing their numbers. This process is called electron cascade, and it plays a crucial role in boosting the brightness of the image.After the electron cascade, the electrons strike a phosphor screen at the back of the image intensifier tube.

As a result, the electrons are converted back into photons, generating a visible green-hued image that we can see through the eyepiece.In summary, night vision binoculars work by gathering ambient light, amplifying it through an image intensifier tube via electron multiplication, and presenting the enhanced image to the user through the eyepiece.
