Transmission assemblies to project illumination from an edge of an electronic device are disclosed. In some examples, the transmission assemblies include an optical source to generate laser light. An optical focusing element to focus the laser light. And a transmitting optical element is arranged at a bezel proximate an external edge of the electronic device. The transmitting optical element receives the laser light from the transmitting optical element and to project the laser light through the bezel to illuminate an object of interest

A device includes a light-emitting device (LED) having at least two vertical light-emitting sides, and a ring-shaped light guide having a bottom side, a top side comprising a light-emitting surface, an inner sidewall, and an outer sidewall defining an indentation having at least two vertical in-coupling surfaces mated to the at least two vertical light-emitting sides of the LED.

An imaging system having a forward and rearward orientation and comprising: (a) one or more parabolic reflectors having a base, a focus, and a reflector axis, said one or more parabolic reflectors defining a central reflector axis; (b) at least one a light source disposed near or essentially at said focus of each of said one or more parabolic reflectors forward of its base; and (c) an imaging device disposed within said one or more parabolic reflectors, and comprising a zooming lens having an optical axis essentially coincident with said central reflector axis.

Ring illuminated surgical cameras and scopes having a ring lens and a plurality of LEDs. The LEDs set behind an electronic imaging sensor (camera) and positioned radially about the longitudinal axis of the lens and/or scope.

A lighting module which provides adjustably controllable illumination of a camera field of view of a camera module includes an adjustable collimator which can be adjustably positioned such that the emitted light beam is adjustably directed to illuminate various regions of various camera fields of view. The collimator can be adjusted via an actuator which adjustably positions the collimator relative to static components of the lighting module, including the light emitter. The light beam can be directed to illuminate a selected limited region of a camera field of view, based on identification of a subject within the limited region. The light beam can be adjustably directed based on user interactions with a user interface, including adjusting the light beam according to user-commanded beam angle, intensity, and direction. The light beam can be adjustably directed to illuminate a region according to different fields of view of different camera modules.

An object is to closely observe, by means of images of a camera having high performance specifications, changes in a structure due to heating or cooling of the structure to a temperature beyond a service temperature limit of the camera having high performance specifications and returning from that temperature to room temperature. A structure observation device includes: a camera case of a rectangular three-dimensional shape, having a glass window of heat-resistant and/or cold-resistant glass on at least one side of the three-dimensional shape; heat insulating walls covering the camera case except for the glass window; a fluid supply port and a fluid discharge port through which a cooling or warming fluid is circulated into; and a camera that is disposed inside the camera case and captures a still image or a moving image through the glass window and externally outputs or internally stores data of the captured image.

A camera apparatus comprising an image pickup device, a lens cover which has an end plate comprising a first plate with a through hole and a second plate positioned in the through hole, and a lens which is covered by the lens cover and converges light from an object to the image pickup device, the light passing through the end plate. A plurality of light sources are arranged to surround the lens in the lens cover and a light shielding member is arranged between the lens and the light sources, and bridges a gap between the first plate and the second plate.

A camera flash is provided with a lens element adjacent a light source, wherein the lens element has a plurality of concentric ridges projecting from a surface of the generally planar member to define facets of a Fresnel lens, and wherein the plurality of concentric ridges define a generally square or rectangular shape having rounded corners.
