ABSTRACT:
An electronic camera module includes a lens or refractive element formed by a pair of immiscible liquids and having optical properties which can be varied by applying a voltage so as to deform the meniscus. One of the two liquids extends from the meniscus all the way to the front surface of the sensor, so that light passing through the meniscus does not encounter further changes in refractive index enroute to the sensor.
