1. An endoscope optical head comprising:
a cavity interposer having a body having a top surface, and a bottom surface, the top surface of the body having a depressed portion forming a cavity at the top surface of the body, the body comprising:
a plurality of first bondpads adapted to couple to bondpads of a chip-type camera cube (CCube), the first bondpads disposed within the cavity and on a base of the cavity at a first level, the first bondpads coupled through feedthroughs to second bondpads on the bottom surface of the cavity interposer at a second level, and
a plurality of third bondpads adapted to couple to bondpads of at least one light-emitting diode (LED), the third bondpads disposed at a third level on the top surface of the cavity interposer;
the third bondpads coupled through feedthroughs to fourth bondpads at the base of the cavity interposer at the second level;
the second and fourth bondpads adapted to couple to conductors of a cable, and
the first, second, and third level being different;
at least one LED, and a chip-type camera cube, where:
the chip-type camera cube is ball-bonded to the first bondpads;
wherein the chip-type camera cube comprises an imaging lens and an image sensor;
the at least one LED is bonded to the third bondpads; and
a top of the chip-type camera cube and a top of the at least one LED are at a same level.
