Abstract:
A variable focus lens has a housing (1) and an actuator (8) which are mutually displaceable along an optical axis (A) of the lens. A primary membrane (15) is arranged between a first chamber (24, 26) and a second chamber (30, 32), with the first and second chambers being filled with liquids of similar density but different indices of refraction. First and second auxiliary membranes (19, 17) are provided for volume compensation. The first auxiliary membrane (19) forms a wall section of the first chamber (24, 26), and the second auxiliary membrane (17) forms a wall section of the second chamber (30, 32), at least one or both of the auxiliary membranes facing environmental air at its outer side.
