Abstract
An exemplary wafer level lens module array includes a first lens array, a second lens array above the first lens array, and a spacer array between the first and second lens arrays. The first lens array includes a number of first lenses, and two first aligning structures. The second lens array includes a number of second lenses, and two second aligning structures. The spacer array includes a number of through holes, and two third aligning structures. The first aligning structures respectively align with the third aligning structures, thereby the first lenses are coaxial with the respective the through holes. The second aligning structures respectively align with the third aligning structures, thereby the second lenses are coaxial with the respective through holes.
Claims14
A wafer level lens module array comprising:
- a first lens array, the first lens array comprising a plurality of first lenses spaced apart from each other, and a first interconnecting section surrounding the first lenses, the first interconnecting section comprising a first surface, and at least one first aligning structure formed at the first surface;
- a second lens array arranged above the first lens array, the second lens array comprising a plurality of second lenses spaced apart from each other, and a second interconnecting section surrounding the second lenses, the second interconnecting section comprising a second surface facing toward the first surface, and at least one second aligning structure formed at the second surface;
- and
- a spacer array positioned between the first and second lens arrays, the spacer array comprising a plurality of through holes spaced apart from each other, and an interconnecting section surrounding the through holes, the through holes allowing light to pass therethrough, the interconnecting section comprising at least one third aligning structure formed thereat, the at least one first aligning structure is aligned with the at least one third aligning structure such that the first lenses are coaxial with the through holes, respectively, and the at least one second aligning structure is aligned with the at least one third aligning structure such that the second lenses are coaxial with the through holes, respectively.
A wafer level lens module array comprising:
- a first lens array, the first lens array comprising a plurality of first lenses spaced apart from each other, and a plurality of first aligning structures at a periphery of the plurality of first lenses;
- a second lens array arranged above the first lens array, the second lens array comprising a plurality of second lenses spaced apart from each other, and a plurality of second aligning structures at a periphery of the plurality of second lenses;
- and
- a spacer array positioned between the first and second lens arrays, the spacer array comprising a plurality of through holes spaced apart from each other, and an interconnecting section surrounding the through holes, the interconnecting section comprising a plurality of third aligning structures formed thereat, wherein the first aligning structures are aligned with the respective third aligning structures, thereby the first lenses are coaxial with the respective through holes, and the second aligning structures are aligned with the respective third aligning structures, thereby the second lenses are coaxial with the respective through holes.
