  • Patent number: 10564380
    Abstract: An alignment mechanism to position and focus a lens assembly includes a housing and an eccentric shaft supported by the housing. The eccentric shaft is configured to rotate with respect to the housing. The alignment mechanism further includes a lens assembly having a bracket coupled to the eccentric shaft, and an actuator assembly, coupled to the bracket of the lens assembly and configured to rotate the lens assembly about the eccentric shaft. The alignment mechanism further includes at least one thrust drive nut mounted on the eccentric shaft, the at least one thrust drive nut being configured to move the eccentric shaft and the bracket of the lens assembly in a z-axis direction.
