Abstract
A camera module includes a lens assembly, a lens holder, and an image sensor assembly. The lens assembly includes a lens barrel and multiple lens elements embedded within the lens barrel. A change of temperature causes an optical focal shift that is determined according to an optical thermal shift rate associated with an optical design of the lens assembly. The lens holder has a lens holder CTE to compensate for the optical focal shift by thermo-mechanical expansion. The change of temperature causes a length expansion of the lens holder determined at least in part according to the lens holder CTE. The image sensor assembly includes an image sensor and a substrate coupled to the image sensor, the image sensor to capture light passing through the multiple lens elements and convert the captured light into image signals. The lens holder is attached to the lens barrel and the substrate using adhesives.
