Abstract: Tunable liquid lens (100) comprising a container (5) delimiting a volume (50), wherein the volume (50) comprises a first liquid (1) and a second liquid (2), a first interface (12) is formed between the first liquid (1) and the second liquid (2), wherein the first liquid (1) and the second liquid (2) are immediately adjacent, a second interface (23) is formed between the second liquid (2) and a third liquid (3), wherein the second liquid (2) and the third liquid (3) are immediately adjacent or the second liquid (2) and the third liquid (3) are adjacent to opposite sides of a membrane (30), the optical power of the lens (100) is adjustable by altering the curvature of the first interface (12) and/or the second interface (23), and the refractive indices and the mass densities of the first liquid (1), the second liquid (2) and the third liquid (3) and the stiffness of the membrane (30) are adjusted to compensate for coma induced by acceleration forces (99).
