- •
A new type of tunable liquid lens operated by electromagnetic actuation is presented and experimentally verified.
- •
To investigate the effect of the electromagnetic actuation on the liquid lens, the sag height and focal length of the liquid lens were tested.
- •
As a proof of concept, the ability of the liquid lens to distinguish two objects positioned at different distances was successfully tested.
