Abstract
In a first aspect, a testing assembly for conducting reliability tests on liquid lenses includes a liquid lens, and a test frame arranged to receive the liquid lens. The liquid lens includes a lens body defining a cavity, a first liquid disposed within the cavity, and a second liquid disposed within the cavity that is substantially immiscible with the first liquid such that an interface between the first liquid and the second liquid forms a lens. The test frame includes a front wall, and a back wall oriented substantially parallel to the front wall. The liquid lens mounts to at least one of the front wall or the back wall and the test frame simulates a smart device incorporating a liquid lens.
