    • An optical apparatus such as a varifocal fluidic lens is provided. Optical apparatus includes a spacer frame, optical fluid, an elastic membrane, an actuator, an actuator frame, and a thermally deformable frame. Spacer frame defines an internal space including a lens portion and a driving portion that connect to each other, and the driving portion is disposed to surround the lens portion disposed in the center area of the internal space. Optical fluid is filled in the internal space defined by the spacer frame. The elastic membrane is attached on a surface of the spacer frame, to cover a side of the internal space, and the thermally deformable plate is attached on the other surface of the spacer frame, to cover the other side of the internal space. The thermally deformable plate deforms to increase or decrease a volume of the internal space according to a change in temperature.
    • 提供了诸如变焦透镜的光学装置。 光学装置包括间隔框架,光学流体,弹性膜,致动器,致动器框架和热变形框架。 间隔框架限定了包括彼此连接的透镜部分和驱动部分的内部空间,并且驱动部分设置成围绕设置在内部空间的中心区域中的透镜部分。 光学流体填充在由间隔框架限定的内部空间中。 弹性膜附着在间隔框架的表面上以覆盖内部空间的一侧,并且热变形板附接在间隔框架的另一个表面上,以覆盖内部空间的另一侧。 根据温度变化,热变形板变形以增加或减小内部空间的体积。
