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.

An optical member driving mechanism is provided. The optical member driving mechanism includes a first portion and a matrix structure. The first portion is connected to a first optical member and corresponds to a first light. The matrix structure is disposed on the first portion and corresponds to a second light, wherein the first light is different from the second light. The matrix structure includes a regularly-arranged structure.

The present disclosure relates to a sensor package, a method of manufacturing the same, and an imaging device that can achieve downsizing and height reduction and suppress occurrence of a flare. A sensor package includes: a solid-state imaging element that generates a pixel signal by photoelectric conversion in accordance with a light amount of incident light; a circuit board electrically connected to the solid-state imaging element; a sensor package substrate that is arranged on an incident light side of the solid-state imaging element and brings the solid-state imaging element into a sealed state; and a lens formed on a lower surface of the sensor package substrate, the lower surface being located on a side of the solid-state imaging element. The present disclosure can be applied to, for example, the imaging device or the like.

Methods and apparatus for aligning a lens holder in a small-height scan engine are disclosed herein. An example method for aligning a lens holder in a small-height scan engine includes: mounting an image sensor to a circuit board; optically aligning, using one or more alignment fixtures, a lens holder holding one or more lenses or optical elements with the image sensor based upon one or more images captured by the image sensor through the lens holder; and after the lens holder and image sensor are optically aligned, physically aligning, using the one or more alignment fixtures, the lens holder with the circuit board based upon a misalignment between a surface of the lens holder and an edge of the circuit board.

A lens assembly includes a lens with a lens barrel and a lens mount assembly. The lens mount assembly includes a lens mount barrel and a protrusion. First threads on the lens barrel and second threads on the lens mount barrel are shaped to permit the lens barrel and the lens mount barrel to be screwed together. The protrusion is positioned to interfere with at least one of the first and second threads as the lens barrel and the lens mount barrel are being screwed together. This interference resists rotation of the lens barrel relative to the lens mount barrel, thereby reducing the likelihood that the lens will be inadvertently screwed or unscrewed away from a desired depth.

A camera module according to the present invention may comprise: a barrel that accommodates a lens therein; a printed circuit board formed under the barrel and mounted with an image sensor; a body portion integrally formed with the barrel; a holder comprising a leg portion formed by being extended downward from the lower end of the body portion to the same height as the image plane of the lens; and a fixing portion formed downward from the leg portion to have a predetermined thickness to fix the holder to the printed circuit board, wherein the thickness of the fixing portion may be equal to the height from the upper surface of the printed circuit board to the image plane of the image sensor.

An optical element driving mechanism is provided, including a fixed portion, a movable portion, a driving assembly, and a connecting assembly. The fixed portion includes a base and a case. The movable portion is movable relative to the fixed portion and is used for connecting an optical element. The driving assembly is disposed between the fixed portion and the movable portion for moving the movable portion relative to the fixed portion. The connecting assembly is disposed between the fixed portion and the movable portion.

An image capturing mechanism is provided, including a base module, a ball element, and a movable module. The base module has a frame, a substrate movably disposed in the frame, and an image sensor disposed on the substrate. The ball element is disposed between the frame and the substrate, whereby the image sensor and the substrate are movable relative to the frame. The movable module is configured to hold an optical element and is movably connected to the base module.

A composition for detecting biofilm on an eyelid margin includes a dye that binds to the biofilm and a solution that is biocompatible with the eye. A method for detecting biofilm on an eyelid margin of an eye includes applying a solution to the eye or the eyelid margin so that a dye in the solution binds to the biofilm. A handheld camera for detecting biofilm on an eyelid margin of an eye includes a housing, an image sensor, and a lens including a focal length determined by a distance between the lens and the eyelid margin. A method for detecting biofilm on an eyelid margin includes capturing an image of the eyelid margin using a handheld camera and determining if the biofilm is present on the eyelid margin. A system for detecting biofilm on an eyelid margin of an eye includes a composition and a handheld camera.
