Abstract
A vehicular camera assembly includes a lens barrel accommodating at least an outer lens element and an inner lens element. An imager printed circuit board (imager PCB) includes an imager disposed at a side. The lens barrel is disposed at the housing such that the imager is aligned with the inner lens element and the outer lens element, with the inner lens element disposed closer to the imager than the outer lens element. A vacuum exists in a space between the outer lens element and the inner lens element to thermally insulate an outer surface of the outer lens element from an inner surface of the inner lens element. Light passing through the outer lens element, the vacuum, and the inner lens element is imaged by the imager.
