Claim:
A tunable lens system comprising: a first fluidic lens element forming a first cavity in which is stored a first volume of a fluidic medium; a first reservoir forming a second cavity in which is stored a second volume of the fluidic medium; a first pressure vessel capable of causing the fluidic medium to move between the first cavity and the second cavity so as to vary an optical property of the first fluidic lens element; a first valve disposed between the first fluidic lens element and the first reservoir, wherein the first valve controls movement of the fluidic medium between the first cavity and the second cavity; a second fluidic lens element forming a third cavity in which is stored a third volume of the fluidic medium; and a second valve disposed between the second fluidic lens element and the first reservoir, wherein the second valve controls movement of the fluidic medium between the third cavity and the second cavity.
