Abstract
Actuators for carrying and actuating a lens having a first optical axis, the lens receiving light folded from a second optical axis substantially perpendicular to the first optical axis, comprising first and second VCM engines coupled to the lens and first and second linear ball-guided rails operative to create movement of the lens in two substantially orthogonal directions upon actuation by respective VCM engines.

An actuator for carrying and actuating a lens holder with a lens, the lens having a first optical axis, the lens receiving light folded from an optical path along a second optical axis that is substantially perpendicular to the first optical axis, the actuator comprising:
- a) a first voice coil motor (VCM) coupled to the lens holder;
- b) a second VCM coupled to the lens holder;
- c) a first linear ball-guided rail operative to create a first movement of the lens holder upon actuation by the first VCM, wherein the first movement is in a first direction parallel to the first optical axis;
- and
- d) a second linear ball-guided rail operative to create a second movement of the lens holder upon actuation by the second VCM, wherein the second movement is in a second direction that is substantially perpendicular to the first optical axis and to the second optical axis.
