    Abstract: The present disclosure relates to a method including providing a die including a cavity therein, wherein the die further may include a die fiducial on a top surface. The method further includes placing a lens structure in the cavity of the die, wherein the lens structure may include a lens fiducial on a front surface. The method also includes moving the lens structure in the cavity to a position until a lens fiducial image may be captured in an image processing system when the lens fiducial and the die fiducial coincide and lie in a plane orthogonal to the top surface of the die. A corresponding system is also disclosed herein.
