The lens module may be a simple optics module and thinner than a related lens module.

A mechanically tunable reflective metamirror optical device for a targeted design optical wavelength includes a dynamically deformable substrate and a sub-wavelength periodic arrangement of patterned isolated gap surface plasmon (GSP) resonators positioned in or on the dynamically deformable substrate. The patterned isolated GSP resonators are movable relative to each other and comprise a patterned optically thin metal layer for the design wavelength, a patterned optically thick metal layer for the design wavelength, and a patterned insulator layer between the patterned optically thin and optically thick metal layers.

A display system and method are disclosed that includes an electronic display device and a backlight comprising a light-emitting array, a reflector adjacent to the light-emitting array, a diffuser opposite the reflector, a first brightness enhancing layer adjacent the diffuser, and an optical film in the backlight unit that includes at least one light conversion material or at least one light conversion material. The light conversion material is structured and configured to reduce hazardous blue light emissions between about 400 nm to about 500 nm. The disclosed display device can include a liquid crystal panel configured to control transmission of light from the backlight to a viewer. The display device also includes one or more optical films that incorporate one or more light conversion or light absorbing materials. The optical films can be positioned between the layers of the disclosed display device and give enhanced blue-light absorption to the display device.

The present disclosure relates to a decoration member comprising a color developing layer comprising a light reflective layer and a light absorbing layer provided on the light reflective layer; and a substrate provided on one surface of the color developing layer, wherein the light absorbing layer comprises a molybdenum-titanium oxide (Mo.sub.aTi.sub.bO.sub.x).

An optical device includes a light guide plate configured to guide light within a plane parallel to an emission surface, and a plurality of light focusing portions to which the light guide plate guides directional light. Each of the plurality of light focusing portions is provided with an optical surface configured to create from the directional light incident thereon emission light in a direction substantially converging on a single convergence point or convergence line in a space or to create emission light that substantially diverges from a single convergence point of convergence line in a space and exits from the emission surface. The plurality of light focusing portions are provided near the emission surface of the light guide plate, and each of the plurality of light focusing portions is formed along a predetermined line within a plane parallel to the emission surface.

A sensor apparatus includes a photosensitive sensor, a cover, and a moving mechanism. The photosensitive sensor includes a first lens and a second lens which focus on a photosensitive element. The cover includes a first slit arranged on an optical axis of the first lens and a second slit arranged on an optical axis of the second lens. The moving mechanism is configured to move the photosensitive sensor and the cover relative to each other so that the second slit is arranged on the optical axis of the first lens.

A folded camera may include folded optics arrangement positioned optically in front of an image sensor. The folded optics arrangement may include one or more light-folding elements and a lens group having one or more lens elements. Light may pass through the folded optics arrangement, within which the light be folded or redirected by the light-folding element, to focus on an image plane on the image sensor. The folded camera may include a shape-memory actuator having one or more shape-memory elements, whose lengths and/or shapes may be controlled by regulating individual temperatures of the shape-memory elements. The shape-memory actuator may move the lens group relative to the image sensor to implement various autofocus (AF) functions. The folded camera may include a voice coil motor (VCM) which may be controlled to move the image sensor relative to the lens group to perform various optical image stabilization (OIS) functions.

An optical image capturing system includes, along the optical axis in order from an object side to an image side, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens. At least one lens among the first to the sixth lenses has positive refractive force. The seventh lens has negative refractive force, wherein both surfaces thereof can be aspheric, and at least one surface thereof has an inflection point.
