Abstract: Manufacturing an optical module includes providing a frame, attaching a light-emitting diode chip and a sensor chip to the frame, and forming overcoats on the light-emitting diode chip and the sensor chip. Each of the overcoats includes a lens. The overcoats can prevent internal chips from being damaged and suffering dust contamination during manufacture.

Abstract: An image capturing device is disclosed. The image capturing device includes: a light-emitting component for generating a light ray; a light-guiding component for providing a first straight light-guiding path to guide the light ray generated by the light-emitting component toward a surface; and a sensor for sensing the light ray reflected by the surface to detect a movement of the image capturing device on the surface.

Abstract: An optical module includes a frame, a light source module positioned at a first end of the frame, and a sensor module positioned on the frame for sensing light emitted from the light source module and reflected from a surface. The light source module includes a light source covered by a first protection element, part of the first protection element forming a lens. The sensor module includes a sensor covered by a second protection element, part of the second protection element forming a lens for focusing light reflected from the surface.

Abstract: An optical device includes a conductive frame, a sensor member mounted on a lower surface of the conductive frame, an aperture member covering the sensor member and having an aperture corresponding to the sensor member, a lighting member arranged on an extension portion of the conductive frame; and a protection member packaging the lighting member and the aperture member onto the conductive frame. The protection member is transparent and made integrally in one piece with the conductive frame, and the protection member has a light-condensing portion protruded therefrom and relative to the aperture and the sensor member sequentially. The lighting member provides light onto an object, which is disposed beneath the protection member, and the light is reflected to the light-condensing portion and further incident into the sensor member via the aperture member.
