Abstract
A vehicular camera module includes a front camera housing portion having an imager, a lens having a plurality of optical elements, and an imager printed circuit board. The imager is disposed at a front side of the imager printed circuit board and the lens is optically aligned with the imager. A rear camera housing portion is mated with the front camera housing portion to form a camera housing. A thermal element is disposed between the imager printed circuit board and the camera housing. The thermal element has a coefficient of thermal expansion (CTE) of 13 ppm/° C. or less. With the vehicular camera module disposed at a vehicle, circuitry of the vehicular camera module is in electrical connection with a wire harness of the vehicle.
