"Liquid Lens And Imaging Device"
Abstract: To provide a liquid lens in which a deformation membrane has a low variation rate in volume caused by-swelling due to liquid, bleeding out of the liquid is prevented, the liquid lens is chemically stable, and a large variable focal length range can be ensured. Included are a pair of transparent members 2 and 3 at least one of which is a deformable deformation membrane and a transparent liquid 4 filling an enclosed space 5 sandwiched between the pair of transparent members 2 and 3. The deformation membrane 3 and the liquid 4 are constituted by a combination of materials below: (1) a fluorinated elastomeric membrane and a silicone oil not having compatibility with the fluorinated elastomeric membrane (2) preferably, a fluorinated elastomeric membrane and a silicone oil having a molecular weight of 500 or more and a viscosity of 50 (25°C mm2/s) or more (3) preferably, a fluorinated elastomeric membrane and a methylphenyl silicone oil or a dimethyl silicone oil having a molecular weight of 500 or more and a viscosity of 50 (25°C mm2/s) or more (4) a polyurethane elastomeric membrane and a dimethyl silicone oil
