Patent ID: 8262566

Claim:
A device for in vivo imaging comprising: a dome-shaped window; a substrate perpendicular to a device's optical axis; an illumination unit; a light guide; an image sensor installed on said substrate, said image sensor centered along the device's optical axis, wherein said illumination unit illuminates an object through said light guide and through said window and wherein said image sensor collects light reflected from the object through said window; a lens holder centered along the device's optical axis and having a first end that is adjacent to the apex of the window, said first end being closer to the apex of the window than the illumination unit and at least partially obscuring a field of illumination of said illumination unit; and wherein said light guide is to guide light from the illumination unit to a light source exit area at the same plane of the first end of the lens holder or at a plane closer to said apex of said window than said first end of the lens holder, said planes being parallel to the substrate plane.
