摘要： 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.

摘要： A wafer-level lens module with an extended depth of field (EDF) and an imaging device including the wafer-level lens module are provided. The wafer-level EDF lens module includes a plurality of wafer-scale lenses stacked with fixed distances therebetween. The plurality of wafer-scale lenses includes an effective lens having a profile which satisfies a corrected optimized aspheric function, wherein a profile of a center region of the effective lens is optimized for an infinity-focused image and a profile of an edge region of the effective lens is optimized for a macro-focused image.

摘要： An optical probe and an optical system therefor are provided. The optical probe is includes a housing configured to house the optical system and the housing has a transparent window therein. the optical system includes a light emitting unit, a collimation lens, and a focusing lens. A numerical aperture of the optical system is adjustable by adjusting a pupil diameter of the collimation lens and a focal length of the focusing lens. The pupil diameter of the collimation lens is adjustable based on a variable focal lens or by adjusting a distance between the collimation lens and the light emitting unit.
