Abstract: An optical zoom in a small form factor suitable for use in mobile devices such as cell phones, security cameras, and other small-scale imaging systems. One or more Alvarez lens pairs are provided, and moved transversely to the optical axis. The combination of one or more Alvarez lens pairs and the actuator permits a zoom power of at least 3× with a lateral displacement distance of the optical components of approximately five millimeters or less.

Abstract: Miniature zoom lens systems and methods of manufacturing thereof are described. An exemplary system includes a first prism positioned to receive incident light from an entrance to the miniature lens system, at least a first varifocal lens positioned to receive the light that exits the prism, at least one base lens positioned to receive the light after passing through the first varifocal lens, a detector positioned to receive the light after passing through the base lens, and a first actuator configured to move the first varifocal lens in at least a direction perpendicular to propagation axis of the light passing through the first varifocal lens. The miniature lens system has a small z-height and can be implemented in mobile devices such as mobile phones.
