Abstract

A camera lens module includes an image sensor and a lens assembly. The image sensor includes a photosensitive chip defining a photosensitive path, wherein the lens assembly is coupled to the image sensor along the photosensitive path of the photosensitive chip. The lens assembly includes at least one optical lens module and an aperture member coupled at the optical lens module, wherein the optical lens module includes a lens barrel and at least an optical lens supported within the lens barrel. A relative position of the lens assembly with respect to the image sensor is adjustable for calibration and the relative position of the optical lens module is permanently fixed after calibration.
