Abstract
Focusing systems and methods for remotely controlling a focal position of an objective lens assembly in a night vision optical device are provided. The focusing system includes a focusing device and a focus selector. The focusing device includes an objective lens assembly positioned among two or more focus positions from an imaging array and a focus controller, coupled to the objective lens assembly, configured to translate the objective lens assembly relative to the imaging array among the two or more focus positions. The focus selector is remote from the focusing device and is configured to wirelessly transmit a selected focus position to the focus controller. The objective lens assembly is translated to one of the two or more focus positions in response to the selected focus position transmitted by the focus selector.
