An optical device for a lens assembly of a camera module is disclosed. The optical device includes a liquid lens having at least one fixed lens and a transparent window, facing each other and delimiting, at least in part, an internal volume containing two immiscible liquids having different optical indices, and a first and a second electrode. The liquids form an interface moveable by application of a voltage between said electrodes. The optical device also includes a liquid lens holder, wherein the liquid lens holder has at least one electrical contact for contacting one electrode of the liquid lens, and at least one Z reference datum for aligning the fixed lens of the liquid lens with other optical elements of the lens assembly.
