摘要： A vehicular camera includes (i) a lens barrel accommodating a lens, (ii) a lens holder having a passageway and (iii) an imager printed circuit board attached to the lens holder with the imager facing the lens. The lens barrel at least partially passes through the passageway of the lens holder when attaching the lens barrel to the lens holder. The imager printed circuit board is attached to the lens holder with the imager facing the lens and optically aligned with the lens. A biasing element urges the lens barrel in a direction outward away from the imager printed circuit board. With the imager printed circuit board attached to the lens holder, the lens barrel is fine adjustable relative to the lens holder. A rear housing attached at the lens holder to encase the imager printed circuit board.

摘要： Present embodiments provide for a mobile device and an optical imaging lens thereof. The optical imaging lens comprises five lens elements positioned sequentially from an object side to an image side. Through controlling the convex or concave shape of the surfaces and/or the refracting power of the lens elements, the optical imaging lens shows better optical characteristics and the total length of the optical imaging lens is shortened.
