Optical device with heating element

An optical device comprising:

• a printed circuit board comprising an image capture electronic circuit;
• a lens holder extending along an optical axis of the optical device from a top extremity to a bottom extremity of the lens holder, said lens holder comprising a top optical element arranged on the top extremity of the lens holder, the lens holder being mounted on the printed circuit board so as to align, along the optical axis of the optical device, the image capture electronic circuit and the top optical element;
• a heating element comprising a heating part arranged in contact with the top optical element and comprising a first electrical conductive wire and a second electrical conductive wire, each electrical conductive wire extending from the heating part to a bottom extremity of the electrical conductive wire, the bottom extremity of each electrical conductive wire having an electrically conductive rigid end that is directly attached in electrical contact with the printed circuit board;
• a first wire insertion guide element, the first electrical conductive wire being arranged in the first wire insertion guide element;
• and
• a second wire insertion guide element, the second electrical conductive wire being arranged in the second wire insertion guide element;
• 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;
• the printed circuit board comprises two pass-through holes from a top layer to a bottom layer of the printed circuit board;
• and
• the electrically conductive rigid end of each electrical conductive wire passes through one of the two pass-through holes and is welded onto the bottom layer of the printed circuit board.
