LIQUID LENS AND IMAGING DEVICE |
摘要 |
<p>Disclosed is a liquid lens that has a low modulus of volume change due to liquid swelling of a deformation film, has no liquid exudation, is chemically stable, and is capable of obtaining a large variable-focus range. The lens has a pair of transparent members (2), (3), at least one of which is formed with a deformation film which is capable of deformation, and a transparent liquid (4) which fills a sealed space (5) sandwiched between the pair of transparent members (2), (3), with the deformation film (3) and the liquid (4) being configured with the following combination of materials. (1) A fluorine-based elastomer film and a silicone oil which does not have an affinity for the fluorine-based elastomer film. (2) Preferably, a fluorine-based elastomer film and a silicone oil with a molecular weight of 500 or higher and a viscosity of 50 (25°C mm2/s) or greater. (3) Preferably, a fluorine-based elastomer film and a methylphenyl-based silicone oil or a dimethyl-based silicone oil with a molecular weight of 500 or higher and a viscosity of 50 (25°C mm2/s) or greater. (4) A polyurethane-based elastomer film and a dimethyl-based silicone oil.</p> |
