摘要： An apparatus for protecting an optical device from contamination is disclosed. The apparatus includes a window disposed between the optical device and a contaminating environment, the window being rotatable about a rotational axis and including an outwardly facing surface that is curved in at least one direction about the rotational axis. The apparatus also includes a bezel enclosing a portion of the outwardly facing surface and defining a clear aperture for transmission of electromagnetic radiation to or from the optical device. The bezel includes a seal extending around a periphery of the clear aperture and is configured to cause the seal to conform to the outwardly facing surface when the window and bezel are urged into contact with each other. The apparatus also includes an actuator operable to cause relative rotation between the window and the bezel to cause the outwardly facing surface to move with respect to the bezel. The apparatus further includes a seal configured to dispense a film onto a portion of the outwardly facing surface that enters the clear aperture during the relative rotation, the film being operable to reduce bonding of optical contaminants to the outwardly facing surface within the clear aperture while transmitting the electromagnetic radiation to or from the optical device through the clear aperture. The seal is configured to dislodge contaminants entrained in the film or adhered to a portion of the outwardly facing surface moving out of the clear aperture during the relative rotation.

摘要： A camera assembly embedded in an electronic device may include a plurality of camera modules, and a supporting frame configured to support the plurality of camera modules. At least one of the plurality of camera modules includes a lens driving assembly configured to move a lens barrel, a lens housing configured to accommodate the lens barrel and the lens driving assembly, a first circuit board on which an image sensor is provided, and a conductive connecting part configured to electrically connect the first circuit board and the lens driving assembly. The supporting frame includes a metal body configured to surround at least portions of edges of the lens housing, and a short-circuit prevention part provided on a surface of the metal body facing the conductive connecting part. The short-circuit prevention part includes a non-conductive material to block electrical contact between the metal body and the conductive connecting part.

摘要： Configurations and compositions for frameworks supporting optics such as lenses are described that provide an invariant structure regardless of temperature swings, thereby maintaining alignment and focus. Frameworks may comprise tiered structures of materials having multiple distinct coefficients of thermal expansion. An optical framework includes a first framework portion coupled to a first lens and a second framework portion coupled to a second lens. The first framework portion and second framework portion comprise materials having a coefficient of thermal expansion such that expansion of the first framework portion in one direction is offset by expansion of the second framework portion in an opposite direction.

摘要： A camera assembly for inclusion in a camera is described. The camera assembly includes a lens barrel and a retaining mechanism that is configured to restrict movement of the lens barrel relative to the retaining mechanism. The retaining mechanism is configured to be attached to a mounting surface of a camera enclosure, such that position of the camera assembly remains fixed relative to the camera enclosure.
