Abstract: A liquid lens can include a cavity, a first liquid disposed within the cavity, and a second liquid disposed within the cavity. A focus of the liquid lens can be adjustable by adjusting a shape of a variable interface defined by the first liquid and the second liquid. Upon adjusting the focus of the liquid lens in a periodic oscillation with a peak-to-valley amplitude of 20 diopter and a frequency of 2 Hz, a root mean square (RMS) wavefront error (WFE) of the liquid lens measured at 1 ms intervals can remain at 100 nm or less throughout one complete cycle of the periodic oscillation.
