Abstract
A camera for a vehicular vision system includes a camera housing having a front camera housing portion and a rear camera housing portion. An imager is disposed at a first side of a printed circuit board. A lens assembly is supported at the front camera housing portion and optically aligned with the imager. At least one attachment element is disposed at the front or rear camera housing portion and has a material having a low CTE that is less than a CTE of the front camera housing portion. The low CTE of the material of the attachment element is less than 10 ppm/° C. The printed circuit board is mounted at the attachment element. The attachment element functions to accommodate temperature-induced movement of the printed circuit board relative to the at least one lens.
