ABSTRACT:
A machine vision image acquisition system is provided with a housing or enclosure that protects the acquisition system components from an industrial environment. The machine vision image acquisition system has a focusing mechanism that can be actuated externally to the housing. The focusing mechanism uses a gear drive to transmit externally actuated focus adjustments to the optical components of the acquisition system.
