Abstract
A night vision device is disclosed. The device includes a housing that houses an intensifier tube and a proximity sensor mounted on the housing. An ON/OFF switch is operatively coupled to the intensifier tube and to the proximity sensor such that operation of the ON/OFF switch to the “ON” position automatically activates the proximity sensor. A method of operating the night vision device with the proximity sensor is also disclosed.
