Abstract: A liquid lens can include a cavity, a first liquid disposed within the cavity, and a second liquid disposed within the cavity. A focus of the liquid lens can be adjustable by adjusting a shape of a variable interface defined by the first liquid and the second liquid. Upon adjusting the focus of the liquid lens in a periodic oscillation with a peak-to-valley amplitude of 20 diopter and a frequency of 2 Hz, a root mean square (RMS) wavefront error (WFE) of the liquid lens measured at 1 ms intervals can remain at 100 nm or less throughout one complete cycle of the periodic oscillation.

Abstract: A selective optical shutter can include a first window, a second window, and a cavity disposed between the first window and the second window. A filter can be disposed in an optical path of the optical shutter, whereby the filter blocks of one of ultraviolet (UV) light or infrared (IR) light and passes each of visible light and the other of UV light or IR light. A first liquid and a second liquid can be disposed within the cavity. The first liquid and the second liquid can be substantially immiscible with each other, whereby a liquid interface is formed between the first liquid and the second liquid. The liquid interface can be adjustable by electrowetting to selectively pass visible light or the other of UV light or IR light.

Abstract: A negative optical power electrowetting optical device is provided. The negative optical power electrowetting optical device includes: a non-conductive liquid having a refractive index; a conductive liquid having a second refractive index; and a dielectric surface in contact with both the conductive and non-conductive liquids. The refractive index of the non-conductive liquid is less than the second refractive index of the conductive liquid and wherein the conductive liquid is immiscible with the non-conductive liquid.

Abstract: A liquid lens system includes a liquid lens and a heating device disposed in, on, or near the liquid lens. The liquid lens system can include a temperature sensor. The heating device can be responsive to a temperature signal generated by the temperature sensor. A camera module can include the liquid lens system. A method of operating a liquid lens includes detecting a temperature of the liquid lens and heating the liquid lens in response to the detected temperature.

Abstract: A camera module includes an image sensor, a lens assembly, and a mechanical actuator. The lens assembly is positioned to focus an image on the image sensor and includes a variable focus lens. The mechanical actuator causes relative translation between the lens assembly and the image sensor in each of an X-direction parallel to a first lateral axis and a Y-direction parallel to a second lateral axis. The first lateral axis is substantially perpendicular to an optical axis of the lens assembly, and the second lateral axis substantially perpendicular to each of the optical axis and the first lateral axis. The lens assembly is fixed relative to the image sensor in each of a first rotational direction about the first lateral axis and a second rotational direction about the second lateral axis.

Abstract: A liquid lens includes a lens body having a first window, a second window, and a cavity disposed between the first window and the second window. A first liquid and a second liquid are disposed within the cavity of the lens body. The first liquid and the second liquid are substantially immiscible with each other and have different refractive indices such that an interface between the first liquid and the second liquid forms a lens. An optical filter is integrated with at least one of the first window or the second window. An image capture device includes an optical system having a variable focus lens, an image sensor, and an optical filter integrated with the optical system. Each of the image sensor and the optical filter is aligned along an optical axis of the optical system.
