Claim 2:
3. A method of assembling an optical device including a lens holder, a printed circuit board supporting an image capture electronic circuit, and a heating element in contact with an optical element, the method comprising:
fixing a first end of the lens holder onto the printed circuit board using an adhesive, the printed circuit board having first and second pass-through holes extending from a top layer to a bottom layer of the printed circuit board;
arranging the heating element on a second, opposite end of the lens holder;
arranging the optical element on the second end of the lens holder and in contact with a heating part of the heating element;
inserting a first electrically conductive wire of the heating element into a first wire insertion guide element;
inserting a second electrically conductive wire of the heating element into a second wire insertion guide element, the first and second electrically conductive wires each having an electrically conductive rigid end;
aligning the image capture electronic circuit with an optical axis of the optical element before the adhesive cures;
inserting the electrically conductive rigid end of the first electrically conductive wire through the first pass-through hole of the printed circuit board;
inserting the electrically conductive rigid end of the second electrically conductive wire through the second pass-through hole of the printed circuit board; and
welding the electrically conductive rigid end of each electrically conductive wire onto the bottom layer of the printed circuit board before the adhesive cures;
wherein the first and second wire insertion guide elements each include an open cavity contained within and extending through a cylindrical wall of the lens holder from an open top extremity of the cylindrical wall to an open bottom extremity of the cylindrical wall.
