In this paper, we report a movable electrowetting optofluidic lens with two liquid‐liquid (L‐L) interfaces. Compared with the conventional tunable lens, the two L‐L interfaces can not only deform the shape, but also move in the cell by an external voltage. The object distance and image distance are adjusted by shifting the L‐L interface position. Therefore, the proposed lens can realize optical axial scanning and zooming. To prove the concept, we fabricate an optofluidic lens and use it as a zoom lens. The zooming range is relatively large and aberration can also be corrected. Widespread application of such a new adaptive zoom lens is foreseeable.
