Vehicular camera module

A vehicular camera module comprising:

• a lens holder formed of a first material;
• a lens barrel formed of a second material;
• a lens comprising a plurality of optical elements accommodated in the lens barrel;
• an imager printed circuit board, the imager printed circuit board having an imager disposed thereat;
• wherein the imager printed circuit board is attached at the lens holder;
• wherein, with the imager printed circuit board attached at the lens holder, the imager is aligned with the lens accommodated in the lens barrel;
• a processor printed circuit board having circuitry that is electrically connected to circuitry of the imager printed circuit board;
• wherein the processor printed circuit board has an image processor disposed thereat;
• wherein the coefficient of thermal expansion of the second material forming the lens barrel is lower than the coefficient of thermal expansion of the first material forming the lens holder;
• wherein the lens holder, the imager printed circuit board and the processor printed circuit board are accommodated within a housing of the vehicular camera module;
• wherein circuitry of the vehicular camera module comprises connecting elements that are configured to electrically connect to a wire harness of a vehicle equipped with the vehicular camera module;
• and
• wherein the vehicular camera module is configured to be disposed at an in-cabin side of a windshield of the equipped vehicle so as to view, when disposed at the in-cabin side of the windshield of the equipped vehicle, forward of the equipped vehicle through the windshield of the equipped vehicle.
