Abstract
Focusing devices and methods for controlling a focal position of an objective lens assembly in a night vision optical device are provided. The focusing device includes an objective lens assembly positioned at a first or second focus position from an imaging device and a binary focus controller, coupled to the objective lens assembly, configured to translate the objective lens assembly relative to the imaging device to either the first or second focus position. The objective lens assembly is translated to either the first or second focus position in response to an orientation of the night vision optical device.
