摘要： A head-mounted device may have a display that displays content for a user. Head-mounted support structures in the device support the display on the head of the user. A lens module in the head-mounted device may include a transparent lens element, a positioner that extends around the periphery of the transparent lens element, and an actuator that selectively shifts the positioner in a first direction. Shifting the positioner in the first direction causes the transparent lens element to be biased in a second direction that is orthogonal to the first direction at multiple points around the periphery of the transparent lens elements. The positioner may be attached to guide structures that each have a respective angled slot. Each angled slot may receive a respective tab of the transparent lens element or a respective tab of a lens shaping element that is attached to the transparent lens element.

摘要： In an embodiment, there is provided an apparatus. The apparatus includes an optic configured for a selected illumination application. The optic includes a first lens structure and a second lens structure. The first lens structure includes a first planar external surface configured to receive incident light, and a first internal nonplanar refractive surface opposing the first planar external surface. The second lens structure includes a second planar external surface configured to emit output light, and a second internal nonplanar refractive surface opposing the second planar external surface. The second planar external surface opposes the first planar external surface. The first internal nonplanar refractive surface and the second internal nonplanar refractive surface define a cavity. The first internal nonplanar refractive surface, the second internal nonplanar refractive surface, and the cavity are positioned between the first planar external surface and the second planar external surface. The first internal nonplanar refractive surface and the second internal nonplanar refractive surface are configured to refract received light to yield emitted light having a target output parameter corresponding to the selected illumination application.

摘要： A lens comprises an internal cavity structure formed by dissolution of a soluble insert material. The internal soluble material may dissolve through a body of a lens such as a contact lens in order to form the cavity within the contact lens. The cavity within the lens can be shaped in many ways and corresponds to the shape of the dissolved material, such that many internal cavity shapes can be readily fabricated within the contact lens. The insert can be placed in a mold with a pre-polymer material, and the pre-polymer material cured with the insert placed in the mold to form the lens body. The polymerized polymer may comprise a low expansion polymer in order to inhibit expansion of the lens when hydrated. The polymer may comprise a hydrogel when hydrated. The soft contact lens material comprises a sufficient amount of cross-linking to provide structure to the lens and shape the cavity.

摘要： The present invention relates to an aperture unit having an optical axis. The aperture unit includes a fixed portion, a guiding element, a first blade and a driving assembly. The guiding element is movably connected to the fixed portion, and the first blade is movably connected to the guiding element and the fixed portion. The driving assembly is disposed on the guiding element for driving the guiding element to move relative to the fixed portion in a first moving dimension. When the guiding element moves relative to the fixed portion in the first moving dimension, the first blade is driven by the guiding element to move relative to the fixed portion in a second moving dimension, and the first moving dimension and the second moving dimension are different.

摘要： An actuator may be integrated into an optical element such as a liquid lens and configured to create spherical curvature as well as a variable cylinder radius and axis in a surface of the optical element. An example actuator may include a stack of electromechanical layers, and electrodes configured to apply an electric field independently across each of the electromechanical layers. Within the stack, an orientation of neighboring electromechanical layers may differ, e.g., stepwise, by at least approximately 10°.
