Abstract
An electrically controllable optical lens apparatus makes use of fixed lenses and an active optical element together in a lens enclosure. The enclosure may be a barrel structure that is easily mounted to a camera device having an image sensor. The active optical element, such as a tunable liquid crystal lens, receives an electrical signal from the camera device via electrical conductors integral with the lens enclosure that provide electrical pathways between the active element on the interior of the enclosure and surface contacts on the camera device. The enclosure may be a two-piece structure, and the electrical conductors may be attached to either piece of the structure. The lens enclosure may also be threaded for attachment to the camera device. The electrical conductors may also use spring loaded contact portions or molded interconnect devices.
