摘要： A packaged image sensor includes a substrate, an image sensor, a light-emitting element, and a first encapsulant. The substrate includes a through-hole. The image sensor and the light-emitting element are disposed on the substrate and are electrically connected to the substrate. The first encapsulant is filled between the image sensor and the light emitting element, and keeps the through-hole of the substrate opened. The through-hole of the substrate of the above-mentioned packaged image sensor can define a relative position between a pipe and the image sensor to facilitate the subsequent packaging process.

摘要： A fundus camera includes an eyeball-offset detection device and an annular illumination device. The eyeball-offset detection device is configured to detect an offset vector of a lens of the fundus camera relative to an inspected eyeball. The annular illumination device includes a plurality of illumination elements that are arranged in a ring shape around an optical axis of an imaging system of the fundus camera. According to the offset vector of the lens relative to the inspected eyeball, the fundus camera selectively activates one or more illumination elements at corresponding positions to keep an illumination optical path away from a center area of the pupil of the inspected eyeball to reduce effects of corneal reflection and improve illumination quality. Therefore, the abovementioned fundus camera has a large operable range.

摘要： A contact-type ophthalmoscope includes a contact lens, an annular illumination module, an imaging lens group and an image capture module. The contact lens having a concave surface is configured for contacting an eyeball. The annular illumination module arranged close to the contact lens is configured for providing a direct illumination light source to illuminate a fundus of the eyeball. The imaging lens group is disposed in the central hollow portion of the annular illumination module and configured for converging the reflected light from the fundus of the eyeball. The image capture module is configured for capturing the reflected light converged by the imaging lens group to form an image. The above-mentioned contact-type ophthalmoscope has advantages of better illumination efficiency, compactness and less scattered light reflected from the imaging lens.

摘要： An ophthalmoscope comprises an illumination element providing an illumination light beam to illuminate the fundus of an eyeball; an imaging lens group converging the reflected light beam from the fundus; and an image capture module. The image capture module includes an image sensing element, a fixation light element and an optical element. The image sensing element captures the reflected light beam converged by the imaging lens group to form an image. The fixation light element provides a fixation light beam passing through the imaging lens group and reaching the fundus. The optical element is arranged among the imaging lens group, image sensing element and fixation light element to make the image sensing element and the fixation light element on different equivalent focal planes of the imaging lens group. According to the above-mentioned structure, a relay lens and a focusing module used by the conventional fixation light element is omitted.
